difference between datastore class method and RPC concerning entity collection

kepmen — Thu, 23 May 2013 14:06:38 GMT

When I call Datastore class method I get an object (EntityCollection) but when I call RPC Module I get an Array!
The problem is that I can�t use this returned array in Client side with setEntityCollection API to refresh my Grid.

My Server Side Datastore class method: (This works fine !)
collectionMethods :
{
getCollection:function()
{
var all = ds.Country.all();
var currentCollection ds.Country.createEntityCollection();
currentCollection.add(all);
return currentCollection;
},
}

My Server Side RPC Module (I get just a Array and NOT entity collection object !)
exports.getCountryCollection = function (){
var all = ds.Country.all();

var currentCollection = ds.Country.createEntityCollection();
currentCollection.add(all);
return currentCollection;
}

My client side Code - Datastore class method :

WAF.sources.country.getCollection({
onSuccess: function(evt) {
debugger;
WAF.sources.country.setEntityCollection(evt.result );
},
onError: function (error) {
debugger;
console.log("Error: USR.testAsync");
}
});

My client side Code - RPC method :
USR.getCountryCollectionAsync({
'onSuccess': function (e) {
debugger;
WAF.sources.country.setEntityCollection(e);
},
'onError': function (error) {
debugger;
console.log("Error");
}
});

Wakand documentaion shows only datastore class method and any RPC call exemple !

Perhaps I am misunderstanding the difference concerning Datastore class method and RPC method as the same code don�t return the same result.

Any help, advise and insights would be greatly appreciated. Thank you!

question about client-side callback function

begincolor — Thu, 23 May 2013 09:22:00 GMT

This is about entityCollection.query() in client-side. Recently, when I use this function in my project, I feel very confused about the execution sequence of its callback function.As show below:
Attachment 2734
myShops is an entityCollection, and it does contain several entities. But every time the judgement below shows the length is 0. When I debug it, I see the code in onSuccess{} is always executed afterwards, after all subsequent code, so the variable items certainly isn't assigned before the judgement statement. Why? How can I control the the callback function's executing sequence to make the following judgement statement meaningful?

Word wrap option for all widgets

kunichan2013 — Thu, 23 May 2013 02:28:00 GMT

I need CSS {word-wrap: normal} property for every gadget and its part with text data.

For example, if a column in a grid has a long name (such as "first assigned status") but the data is 1 byte, I want to display the column title in 3 lines like

first
assigned
status

If there is a Text style option "Word Wrap" in the "Styles" tab of a grid design, it will be very convenient to do such customization.

Of course if I want to display long text (such as 100 bytes of text) in a column with 30 bytes width, this new option is quite useful.

Solved Slider - WAF-Error

Ronald Pfitzer — Wed, 22 May 2013 15:40:39 GMT

Hi,

since some days (?) I cannot use the slider widget. I can simply reproduce this issue with a newly created solution and only one slider widget on the page. The WAF throws following error in line 36703 of waf-optimizie:

Code:

Uncaught TypeError: Cannot call method 'done' of undefined

Code:

German number input with comma

gmu — Wed, 22 May 2013 08:25:18 GMT

In the grid my number data was display in german style.
I have set the number format of the data cell to "###,###.00".
In german browsers he displays a number correct like this 123,56 (US-Browser displays 123.56)

If i want to input a number with comma (,) as decimal point, he ignore the rest of the Input:

Input 123,56 -> Displays 123

Only the point (.) as decimal point works:

Input 123.56 -> Displays 123,56

Is it possible to change this settings?
I think many No-US-Users need this.

Thanks

Unable to Create Project: Wakanda v 4.132351 & OSX 10.6

nutsoa — Tue, 21 May 2013 02:33:01 GMT

I am testing Wakanda v 4.132351 with OSX 10.6.8 for the first time. Trying to follow the start up guide.

Installing it from scratch, I have copied applications like this : /Applications/Wakanda Server.app
and /Applications/Wakanda Studio.app.

I am unable to create a New Project. Menu and icon stay grey.
This is a new installation I can't have done anything wrong, is this a bug or do I have forgot anything ?

One more, I can't open Wakanda Preferences. Nothing happens when I select the preferences menu.

For both case, I tried to erase ALL Wakanda Server and Studio files in ~/Library/Application Support and re-run, but observe no change.

Thanks for help.

Learn Wakanda while you code and make the IDE 10x's more useful

Tut — Tue, 21 May 2013 01:03:43 GMT

In the explorer pane (or another pane), don't just list project files:

- have nodes for all of Wakanda's API's (and even for Javascript)
- list all available functions
- tooltips for everything summarizing node|function
- fast way to move selected function over to cursor position in code editor
- fast way to move example code for selected function over to cursor position in code editor

Say I forget how to select the next record. Instead of digging around in the docs I peruse the Wakanda api nodes...see "datasources"...see "selectNext"...see the tooltip for selectNext...say to myself: "lets try this one"...hit "move function over" -- and it's in my code.

something about entityCollection

begincolor — Mon, 20 May 2013 02:49:35 GMT

I find that an entityCollection can only add entities which already existed in the database. If I just add a new instance, it doesn' work.
part of my code is like this:

var bags =ds.Bag.createEntityCollection();
var bag=new ds.Bag({
name:"knife",
quantity:2
});
bags.add(bag);
bags.length;

The console shows nothing.
but if I add the save(),it works:

var bags =ds.Bag.createEntityCollection();
var bag=new ds.Bag({
name:"knife",
quantity:2
});
bag.save();
bags.add(bag);
bags.length;

The console shows "1".

I've no idea why we have to add an persisted data into a collection, rather than just add a temporary entity?
I think it is not good to always persist unnecessary data before I use them. Hope someone could give me the answer.

is v4 directory buggy with includes groups?

vegarringdal — Sun, 19 May 2013 16:46:56 GMT

Attachment 2719

I got 2 users.
admin/admin and test/test
Admin group is needed for doing anything in the class
User admin is part of group admin
And user test is part of the other group that includes admin.

For me to be able to do anything my test user needs to be part of admin group, and this makes no sense, or admin group needs to include the other group.

Should it no be enough that my other group to inludes admin group, and get admin permission too?
And if no users if part of admin group, then the database do not use any permission at all, it's wide open.

cannot create entity from a inherited class

bonjourscott — Sun, 19 May 2013 14:45:11 GMT

Hi everyone,

I got a problem in creating entity from a inherited class.

As you can see, there are two classes, the Weapon inherits from Weapon_model.
Attachment 2718

I was trying to create a Weapon entity in a testing page:

Code:

var buy = ds.Weapon.createEntity();



buy.id = 20;

buy.type = "fork";

buy.power = 100;

buy.hit_ratio = 100;

buy.hit_per_second = 1;

buy.price = 100 ;



buy.save();



var typeName = buy1.getDataClass().getName();

It return no errors, but when I check the Data Browser, I could only find this entity was in the Weapon_model table...I am confused....

Could anyone figure out the reason?

Notes in Model APIs (v5).

info@adgrade.it — Fri, 17 May 2013 12:45:59 GMT

1)
Is it possible to add "notes" into the option of the "Attribute()" and "DataClass()" constructor?
Now it is impossible to have notes creating the model via APIs.
I think that the model APIs have to give us the choose to manage all the properties of the model visible into the gui model editor.

2)
I see that the notes of inherited attributes of extended classes are not displayed into the gui model editor, why?

3)
What do you think about the permissions?
Why don't define also the permissions via APIs?

Best regards.
Alex.

Notes in Model APIs (v4 and v5).

info@adgrade.it — Fri, 17 May 2013 10:17:06 GMT

Using Model APIs (v4 and v5) I note that I can't define notes for Classes and Attributes created.
I think it is missed the option "notes" (like simpleDate, scope, limiting_length and so on...).

Also, I note that in the gui model editor, there are not the notes into the properties pane of the inherited attributes of extended classes.

An other observation: in the documentation v5 -> "attribute" is missed the kind "removed" (used to remove an inherited attribute).

Best regards.

Any way to move widgets from one container to another ?

gaurav — Fri, 17 May 2013 09:14:10 GMT

Is there some way to move a widget from one container / view or parent widget to another widget ?
In Wakanda Studio, under 'Outline' tab, I think the widgets should be drag-able to move them to different place on page or widget container.

If there is some way to move widgets, kindly suggest.

Roadmap - 5/15

lweidig — Fri, 17 May 2013 03:12:40 GMT

First, was a bit surprised to see the Roadmap updated since it was stating the next update was to be 5/21 but I am glad to see it and really like the new format.

What is really NOT nice about the roadmap is that all of the things I have been waiting for in 5 have now been pushed off to 6! Are we really MANY months away from addressing the Widget API, theming? Not to mention I do not even see reporting on the roadmap which is key for many. From what I recall in one of the webinars the version release cycle is planned at about 3-4 months. What happened?

I love the tool and have been using it quite frequently. Hate to see much needed features sliding out further. Thanks!

[SUGGESTION] - Suggestion to improve searching in online documentation ?

gaurav — Thu, 16 May 2013 13:38:00 GMT

I think there is lot of documentation on Wakanda, but things are not easy search and find. Most of the time I do not find things n documentation without fighting with it.

I persoanlly like the way SmartClient has created their documentation. Its easy and quick to search. You directly find things you are looking for.

Can you check below link as a reference.
http://www.smartclient.com/docs/8.3/...lass..ListGrid

I would appreciate if wakanda team can also brainstorm to improve the documentation from search point of view,I think most of the wakanda developers will appreciate it.

Logfile double entries

Michael Hong — Thu, 16 May 2013 06:34:05 GMT

Hi,

is there a reason why a "console.log" creates two entries in the log file (Logs folder).
For example:

Code:

console.log("17:12:31, 2013/05/15: running... (SystemGlobals)");

creates

Code:

2013-05-15 17:12:31 [com.wakanda-software.webclient.client] INFO - {"data":["17:12:31, 2013/05/15: running... (SystemGlobals)"]}

2013-05-15 17:12:31 [com.wakanda-software.webclient.client.console] INFO - {"data":["17:12:31, 2013/05/15: running... (SystemGlobals)"]}

And is there an option to turn that off? Every line gets doubled, which is a bit useless and makes the log harder to read.

How to make client and server communicate ?

gaurav — Wed, 15 May 2013 03:46:07 GMT

I am asking very basic question, but this is something I am not able to achieve. I think of will take me some time to learn wakanda way of programming :-)

In my trial mobile app, I have two views. View 1 contains the search form with few fields. When I fill the form and click on search button, I move to next view which is bound to data source. View 2 by default shows all the entities in that related data store and do not fetch entities based on search parameters. How can I fetch only the required entities based on search parameters input in view 1. I just want to show entries which have given keyword in either title, description or tag attributes of entity. Later on might replace the filtering criteria based on some business logic on server, for instance returning all entities with near by geo location based upon given latitude or longitude.

Moreover can someone explain what is the best way in wakanda to make client communicate to back end. I think there are multiple ways to achieve it - client calling data store methods on server (RPC), REST calls, calling client data store methods, using data provider APIs etc.

Regards,
Gaurav

extended classes and relational attributes

pkesch — Tue, 14 May 2013 20:11:57 GMT

this is just to confirm that I am not overlooking something...

here are some statements about extended classes and relational attributes. Please correct me if I am wrong:

1. an extended class can have a relational attribute of type 1->n pointing to a base class

2. an extended class can NOT have a relational attribute of type n->1 pointing to a base class
(this would mean that a storage attribute would have to be created in the extended class to store the reference which is currently not possible)

3. an extended class can NOT have a relational attribute of type 1->n pointing to an extended class
(this would mean that in the "other" extended class there would have to be a storage attribute to store the reference)

4. an extended class can NOT have a relational attribute of type n->1 pointing to an extended class
(same as in 3)

This means that in extended classes it is only possible (currently) to have a relational attribute of type 1->n to a base class.

(I know that there is the workaround to create the n-1 relational attributes in the base class... this is just to confirm the current limitations)

Am I right? If yes I think this should be mentioned in the doc somewhere! Especially when newcomers try to figure out the best way how to design their models.

Cheers

Why I cannot persist the entitycollcetion in a entity from the 1(1 to N) side?

begincolor — Tue, 14 May 2013 11:17:23 GMT

For example, if I define 2 datastore class :Employee, Company.
In Company, there is an attribute "employees", which related to the Employee as 1 to N relation.
When I　new an instance "company", and use company.employees.add(emps), emps is an entitycollection with type Employee, then company.save(). But the databrowser show there is nothing in the employees of the new record. I tried to bound them reversely from Employee side, it's OK, but I think it is too trouble to do that one by one. Can somebody tell what's the problem with persisting the entitycollection, and how to achieve that in wakanda?

Best way to create large model.

info@adgrade.it — Tue, 14 May 2013 08:28:44 GMT

I actually use Wakanda 4 last version.

I start to create a large model (more than 200 classes).

Now I have a doubt: in wakanda 4 we have APIs to create the model but, into the next version (wak v5) theese APIs changes.
Also, the easiest way to create classes and attributes is via graphical interface, not using APIs.

My application is a kind of work in progress and needs continuous updates also after the release, so my priority is to have a good kernel (model/modularity and so on...) in order to maintain the application clean.
The model have to be up to date also with v6, v7...

So, how start to create my model from scratch?

graphical interface + free form
APIs v4
APIs v5 (waiting some months)

What are the costs / benefits of the techniques above?

Best regards

Problems with the function "mylogin"

dsantiago — Mon, 13 May 2013 09:18:15 GMT

Hi all,

I want to use a custom datastore class to authenticate login requests and I'm having trouble running the following function:

(this code is the documentation of wakanda: http://doc.wakanda.org/Users-and-Gro...871936.en.html)

In the "bootstrap" of the project, we define a loginListener:

Code:

directory.setLoginListener("ptoLogin", "Internal");

    // I want the listener to be run with the internal group's privileges

In the "scripts/required.js" file, I write the "ptoLogin" function:

Code:

function ptoLogin(userName, password){

        

    var p = ds.Usuarios.find("NombreAcceso = :1",userName);// 

    if (p == null) 

        return false; 

    else

    {

       if (p.Password == password)   {

   

            

      

         var theGroups = [];

            

            switch (p.accessType){

                        case 1:

                        theGroups = ["Internal"]; break;

                        case 2:

                        theGroups = ["Trabajador"]; break;

                        }

                        

     

                       

            var connectTime = new Date();

            

            return { 

                ID: p.ID, 

                name: p.NombreAcceso, 

                fullName:p.NombreAcceso,

                belongsTo: theGroups,

                storage:{

                    time: connectTime

                }

            };

       } else {

            return { error: 1024, errorMessage:"invalid login" };

    }

    

        }

};

And when I start the debugger before the red code:

Source code is not available.

immediately starts a function of wakanda:

Code:

RestDirectoryAccess.currentUser = function() {

        var user = currentUser();

        if (user == null)

                return null;

        else {

                if (user.ID === "00000000000000000000000000000000")

                        return null;

                else {

                        return {

                                userName: user.name,

                                fullName: user.fullName,

                                ID: user.ID

                        }

                }

        }

}

This function is in directoryRest.js

Any suggestions for good return user data?

It may be for the version of wakanda?

Solved Extended Public DataClass got error showing relational sources

Hi,
I don�t know if it�s a bug...

1.- Create DataClass "Students"
2.- Add attributes (name, last, ...)
3.- Create DataClass "courses"
4.- Add attribute (number, description,...)
5.- Create a 1->n relational attribute "studentCourse"
6.- Create a new page with DataGrid with "students" source and other dataGrig with "studentCourse" data.

Works Fine.

7.- Extend DataClass "Students" -> "StudentsExtended".
8.- Change scope of "Students" to "Public on Server".
9.- Change Datagrid source on page by "StudentsExtended" (public)
10.- On console:

Matrix display problems.... makes it unusable

AudioFreak — Sat, 11 May 2013 18:28:17 GMT

I have a matrix that i use to display a form with the content of a table. The thing is that I try to create a fully resizable application that can be used in any window size (with a given minimum, of course), but I want my matrix elements to always look like a list and not a grid.

What I did is to add some size constraints to my form so its container will always take the full width of the matrix. It works fine until the scroll bar appears. When that happens, the container of the form is not resized and the right end of the form is hidden under the scrollbar.

Then I tried to just make the window smaller just in case it was some refresh that didn't happen, but at that moment the content of the matrix disappeared and I had to maximize the browser again so the content would be visible again... with the right end hidden under the scrollbar.

Is that a known bug? Because that makes the matrix (which is one of my favorite widgets because of what it let you do) unusable in a fluid design and it's really really sad...

thanks!

Bad reflex coming from my Delphi and VB years?

AudioFreak — Sat, 11 May 2013 17:09:59 GMT

Hi all,

I just want to know if I'm in the wrong, because it seems to break stuff when I do it. I come from a big Delphi and Visual Basic programming background and the way we used to work is to name every component in the window we are designing. So, in wakanda, when I add something like a tab panel, I have a tendency to rename every generated widgets so they represent what they are used for. I don't like having something like $('container5') when i could have something explicit like $('tabGeneralOptions').

I've read a lot of the documentation, especially the Getting Started thing, I've watched webcasts, and stuff, but I can't say that I noticed anyone renaming the inner components of a widget like a tab panel or a menu bar.

I already tried renaming stuff, but it seems to break the widgets. Was I just unlucky or it's the way it is?

Thanks in advance!

Mobile App - How to show info from DB in our own layout ?

gaurav — Sat, 11 May 2013 13:48:05 GMT

We are tryin to build some mobile app using Wakanda and want to show info in our own layout (other than grid or list view etc). How can we show dynamic info (from DB) in our own layout, Is ther already some widget for this ow we need some alternate way to achieve it.

Below is the layout which we want to achieve. Before this UI there will be a list view UI showing all entities of interest. User will touch anyone of the entities to reach at this screen. This screen shown pull the selected entity details and should show in this layout or some other layout of our choice:

file upload widget - blob

robkanda — Fri, 10 May 2013 21:11:36 GMT

According to the documentation it should be possible to use the file upload widget to upload a blob (pdf file) to an attribute in the datastore with type BLOB. When I try this the the attribute stays null.

I do have a current element and I get the display notification that the file is uploaded (but that's a lie).

When I change the type of the attribute to image it does work. When I check the size of the attribute it is exactly the size of the pdf file I chose.

Tip, pdf printing/generate with jspdf.com on server side

vegarringdal — Fri, 10 May 2013 17:20:19 GMT

Here is my tips

www.jspdf.com
download it

server side:
rename line 49 and 143 in the jspdf.js from window to application, and it works fine on server side

start with this in the rpc module (with your path)
include(ds.getModelFolder().path + 'developmentScripts/jspdf.js');
include(ds.getModelFolder().path + 'developmentScripts/jspdf.plugin.split_text_to_size.js');
include(ds.getModelFolder().path + 'developmentScripts/jspdf.plugin.standard_fonts_metrics.js');

created and when generating it do this;

var string = doc.output('datauristring');
and return the string

return string;

on client side

call your rpc, async might be better... (this is actuall where you start!!)
var string = print.printWPtest(waf.sources.workpack.name);

and pass the string to a iframe
$("#printComp_frame2-frame").attr('src', string);

Is Wakanda mature for Mobile App Dev ?

gaurav — Thu, 09 May 2013 13:45:23 GMT

First let me tell that I am new to Wakanda but have decent experience playing with SmartClient JS framework. Frankly saying, I am loving what I am seeing and reading about Wakanda since last few days. To me its one of the best and most comprehensive solution to build web apps; including both frontend and backend, but I am not sure on its capabilities to develop run-time optimized mobile apps.

Can someone having decent experience with Wakanda put some light on pros and cons of using Wakanda for cross platform mobile app development. Is it optimized (performance wise) for mobile app ?

I am also reading a lot about Sencha Touch and its looks great tool to build mobile apps, but it lacks the backend development of Wakanda.

One key difference I could figure out between Sencha Touch widgets and Wakanda widgets is that Sencha widgets are completely written in JS whereas Wakanda widgets are in HTML. Will it impact the performance of mobile app?

As per my understanding the JS UI of Sencha Touch will load once and thereafter will get and post data to web server using JSON, where as Wakanda widget (HTML) will load on every request or view change, further doing the JSON request to server. So if I understand correctly Sencha Touch is more light-weight than Wakanda in terms of client server communication, am I right ? Correct me if I am wrong.

Moreover I think Sencah TOuch have much wider options of widgets for Mobile as compared to Wakanda mobile widgets, which make it more interesting UI designing, but Wakanda seems good for Server based logic, so good combination would be to have Sencha Touch widgets available in Wakanda Studio as its native widgets. I think this will make Wakanda immediately ready platform for mobile app development.

Need opinion from Wakanda experts to understand better and evaluate Wakanda again Sencha Touch to develop real business mobile app. Please share your thoughts.

Import MySQL data into Wakanda data store.

fxleytens — Thu, 09 May 2013 08:07:14 GMT

Hi,

I am currently VERY new to Wakanda and I would like to evaluate it to replace an old fashion php application.

I am running a LAMP web application that has been coded with the foot quiet long time ago. Today, maintenance is a real nightmare. I would like to change to something more "sexy" and more 2013 style.

I have tryied Wavemaker from VMWare and this looks quiet promising but "on the paper", Wakanda seems to be more suitable of what I want.

The problem is that I have a relational database of 10'000+ rows and 9 tables, that sits on my MySQL database. I don't mind to switch to the Wakanda datastore but I need to import all those data to it.

I have found a tutorial (http://www.tuicool.com/articles/yY7neu) that explains how to import one single table.

Can anyone point me to a place that explains how to do ? Knowing that I can also export my tables in CSV.

Many thanks

Suitable for photo sharing app ?

webb — Thu, 09 May 2013 01:36:03 GMT

Greets,

I just discovered Wakanda a few days ago and so far it looks like it might be exactly what I've been looking for. I do have a question though... I'm developing an Android/iOS photo sharing app using Xamarin. Would Wakanda be a good (great?) fit for the server side? Storing the pictures, location data, etc etc. Of course, I'd need it to be able to scale across servers when necessary. :)

I prefer to develop in JS, so I hope this will work without too much fuss.

Thanks!

Reading/writing data to the Wakanda DataStore from an outside application

tiredoftry — Wed, 08 May 2013 16:28:27 GMT

How would it be possible to query/write data from the datastore from an outside application? I work with an application which uses VoiceGuide to handle touch tone parts of an application. VoiceGuide queries the current database checking for available reservation times and allows the caller to book a reservation for any available times. This reservation is written into the database and a confirmation message played to the caller. Is there a tutorial or documentation page with more information on this type of reading/writing?

onInit on base class and on inherited class, should this work?

pkesch — Wed, 08 May 2013 10:30:56 GMT

Hi,

I have a base class "A1" with attributes "name", "attribute1" and "attribute2".

A1 has an onInit event where I assign a value to attribute1.

This works (using my own form, not using the grid... see also previous threat)

I also have an inherited class "A2" with "A1" as a base class.

A2 has also an onInit event where I want o assign a value to attribute2.

Now, creating a new record in A2 does not execute the onInit event of the A2 class, only the onInit event of A1 is executed.

Question: is it not possible to have an onInit event on the base AND on the inherited class???

I think it definitely makes sense to have such events on both classes....

Cheers

P.S. this is the same issue which was reported in August 2012 WAK0078029

I did not need it so far therefore I did not follow up since. But now I would really need this.
It is definitely reproducible and I could provide a sample project and a screencast if necessary!

data entry via grid widget does not assign values in the onInit event

pkesch — Wed, 08 May 2013 09:29:05 GMT

Hi,

I have a ds class "A1" with attributes "name" and "attribute1", both strings.
The class has an onInit event where I assign a value to the attribute1.
(very simple, just for test purpose: this.attribute1 = "hello")

Now, when I use my own form to enter records all works fine and the attribute 1 is filled.

Entering data using the grid does not assign the value to attribute1.
The onInit event is executed (tested it with the debugger) without error but the attribute1 does not get the initial value.

Is this a known problem? I did a search with "onInit" in the bug system but found no records.

Cheers

Tablet page doesn't fit with the tablet device screen size

Gabriel Inzirillo — Wed, 08 May 2013 09:24:48 GMT

Hi

I have the problem that my tablet page doesn't fit with the tablet screen size. It should fit to the windows depending of the screen size of the device, shouldn't?

When I created my page, the Workspace width and height have been defined and now I can change those values (in the body tag) but it will only fit if I choose to put my web app in the menu home of my ipad so that I don't have anymore the address bar.

I have reported as a bug (WAK0077534) but it still tagged as "Incomplete Informations" But with the 4 steps I indicate in the bug, everybody can reproduce it.

So how can we do to have a content who can fit to the screen size, without regarding what we have define when we have created the page?

Thanks

customized sorting for calculated attributes

wei — Tue, 07 May 2013 21:07:12 GMT

Hi, there,

I am working on a project that requires customized sorting for calculated attributes:
I have a Order class, which has a 'status' attribute (this is a calculated attributes, its value can be one of 'received', 'processing', 'cancelled' and 'finished').

Order datasource will be sorted based on each order's status by default. This means that if you sort orders by status using 'ascending', 'received' orders will come first in the grid, followed by those orders whose status is 'processing', then 'cancelled' orders and ' finished' orders. If you sort orders by status using 'descending', 'finished' orders will come first, then followed by 'cancelled' orders, then 'processing' orders and 'received' orders.

I think On Sort method for a calculated attribute is for this purpose. But how to make it follow certain sorting rules like ('received', 'processing', 'cancelled' and 'finished')?

There is a similar thread http://stackoverflow.com/questions/4...et-field-value. This thread discussed custom sorting in MySQL ( ORDER BY [custom SET field value]).

In MySQL, you can do it like this:

Code:

.. ORDER BY CASE `status` 

                WHEN 'available' THEN 1

                WHEN 'busy' THEN 2

                WHEN 'distance' THEN 3

                WHEN 'offline' THEN 4

             END

How can we achieve this in Wakanda?
Thanks

Loosing Current Entity reference

lordwhiskey — Tue, 07 May 2013 08:50:41 GMT

Hi,

i'm building a simple app based on components with multiple pages where user can interact.

For example i've datasource1 displaying its contents into a data grid.

I'm trying to make possible to modify records in data grid double clicking on a record.

For example:

Double click on row 2, there's an event behind this action that loads the component with form containing all the text fields and other widgets concerning the current entity in the entity collection.

Here i can modify the current record values and store them or cancel the operation.

The strange thing is that the first time i make this action (so double click on a random row) i'm redirected to the form component page and get the correct entity inside the different text inputs and so..

The second time I try to modify a record, clicking on it in the data grid, i'm redirected ti the component page with form but the entity selected is not the one clicked.

Someone can help me?

Thanks

Using existing git repo

Michael Hong — Mon, 06 May 2013 12:54:36 GMT

Hi,

I've been using git since before Wakanda even became version 0.5 :RpS_thumbsup:. (We're pushing to our own inhouse git server)
There is a .git repository inside the solution folder. Every git-application, that I use, ie. TortoiseGit, SmartGit, Tower (MAC), Eclipse with eGit recognizes the repo and its settings automatically.

Code:

c:\all_wakanda_solutions\mysolution1\.git

c:\all_wakanda_solutions\mysolution2\.git

c:\all_wakanda_solutions\mysolution3\.git

Wakanda seems to expect the .git repo to be at the same level of the solution folder.

Code:

c:\all_wakanda_solutions\.git

c:\all_wakanda_solutions\mysolution1

c:\all_wakanda_solutions\mysolution2

c:\all_wakanda_solutions\mysolution3

Doesn't this mean all solutions share the same repo?
Is there a way to configure git, where the repo is located?

Sencha Touch widgets + Wakanda Backend - How to Start ?

gaurav — Sun, 05 May 2013 14:56:38 GMT

Hi,

I am new to Wakanda and is exploring its potential for quick mobile app development. As per my current understanding Wakanda have robut ans scalable backend and even elegant front end for web app but the front end (widgets) might not be optimized (performance wise) for mobile platform, so I am exploring if we can integrate Sencha Touch 2.2 widgets in Wakanda Studio to replace Wakanda native widgets but keeping the same Wakanda backend.

I am sure there is some way to do it but do not know how exactly to do it. I will appreciate if someone can show me some working example or code so that I can learn from it.

Kindly help if you know the way to integrate Sencha Touch widgets to Wakanda back-end.

Dynamically assigning the datasource

North2Alaska — Sun, 05 May 2013 11:34:52 GMT

I posted this question in the General Discussion forum, but have had no response so I thought I would try here too. Sorry for the duplication.

-----

My main page consists of a navigation area and a component. I change the component based on the buttons selected in the navigation area. I load the component with a component that contains a tab view widget. In the second tab I display the details of a record in a container. In this container I also have a reference to another component. This component contains several buttons that will act on a record.

The organization looks something like this:

index.html
- Component (mainComp)
-- Loaded Component (projects.waComponent)
--- Tab View (projTabs)
---- Tab Container (projDetailsCont)
----- Container (projContDetails)
------ Component (recNavCompDetails)
------- Loaded Component (recNav.waComponent)
-------- Container (recNavCont)
--------- Image Buttons (recNavBtnFirst, previous, next, last, cancel, remove, create, save)
Attachment 2675

What I would like to do is make these buttons work for a dynamically assigned datasource so that I could reuse the button set for another datasource on a different page.
Questions:
1) What is the best way to reference the buttons?
2) How do I assign the datasource to each button?
3) How do I assign the datasource action to each button?
4) How do I center the recNavCompDetails component in the Tab Container?

OBCD driver for wakanda ?

gery51 — Sun, 05 May 2013 07:09:54 GMT

Would it be possible to develop an OBCD driver for WAKANDA ?

This would help many professionals to keep their external software like report-writers and so on, working without
Fuss.

When they see the much greater possibilities and power of wakanda they will without dougt totally proceed to it.

It would makes the it-people possible to GRADUALLY go over to the new software.

No firm would like to change so dramatically at once.

var name, indexSeparator, value;

if (header.indexOf('HTTP/1.1') === 0) { // this is not a header but a status
return; // filter it
}

indexSeparator = header.indexOf(':');
name = header.substr(0,indexSeparator);
if (name === "") {
return;
}
value = header.substr(indexSeparator + 1).trim(); // clean up the header attribute
headersObj[name] = value; // fills an object with the headers
});
if (headersObj['Content-Type'] && headersObj['Content-Type'].indexOf('json') !== -1) {
resultObj = JSON.parse(result);
} else {
resultTxt = result;
}
};

xhr.open('GET', URLText); // to connect to a Web site
xhr.setRequestHeader("Content-Type","application/x-www-form-urlencoded");
xhr.send(isRequest);
statusLine = xhr.status + ' ' + xhr.statusText; // get the status

var retValue = {
statusLine : statusLine,
headers : headersObj,
result : resultTxt,
contentL : contentLength
}
return retValue;
}

I get only "OK" in the resultTxt.

What am I doing wrong?

Many greetings

List View and Array Datasource

earth01 — Thu, 02 May 2013 12:59:38 GMT

Hello,

I've been able to make array datasources work with Grids, but not with List Views.

Has anyone encountered this bug, or is this an intended behavior ?
Is there a workaround ?

Thanks :RpS_smile:

cannot call datastore class method from client-side?

begincolor — Thu, 02 May 2013 11:59:37 GMT

When i debug my client-side code, it breaks right on the method calling which i definded on datastore class.
likeAttachment 2667
In model designer, I set the method scope to 'public' and checked carefully the method name spelling, why I cannot yet call it in client page? All datastore class methods can be called in server-side scripts, which I've tested, but it failed when being called on client page. I fell fairly strange,or is there anything I missed setting?

Is there 1 to 1 relation in model datastore design?

I find there is only 1 to N mapping in options of type, but I need to build 1 to 1 for my particular two classes. I wonder if there is 1 to 1 option in wakanda datastore class design, or it is conceptually included in 1 to N relation in this case?

And when i directly click the tab Attachment 2656,it displays like thisAttachment 2657. even though I wirte hard-code "debugger" in my code, it still does not work.

Database data file is corrupted

Michael Hong — Mon, 29 Apr 2013 10:41:17 GMT

Hi,

we have some test environments here:
- OSX 1 native
- OSX 2 virtual machine
- OSX 3 native
- Win 1 native
- Win 2 virtual machine

OSX 1, OSX 2 & Win 2 are running permanently.
Since the update to WAK4, OSX 2 regularly gets the error:

Code:

2013-04-29 04:29:14 [com.wakanda-software.webclient.client] WARN - Error opening data file

2013-04-29 04:29:14 [com.wakanda-software.webclient.iasv] ERROR - [1035] Cannot open the database

At first we thought that maybe there's something wrong with the VM, where OSX 2 (with most traffic, since we have test users testing all the time) is running. But during the weekend OSX 1 also crashed with that message in the logs and could not be restarted.
I'm beginning to be worried, that there's something wrong with the server, although it seemed to be rock-solid the most reliable component of Wakanda.

Anyone has experienced this? I've seen a bug-report WAK0081782, but I think, that's a different context.

Git error: The remote end hung up unexpectedly

Peter Vogel — Sun, 28 Apr 2013 20:36:42 GMT

Hi,

using 4.131311 i tried to set up a git Push to Solution Server from my local Studio running on OS X 10.6.8 to a Windows 2008 R2 Server on the net.

I installed a local git repository (git version 1.7.12) and checked that git (version 1.7.11) was installed on the windows server 2008.

When i tried my first push after copying my local solution to the remote server and doing a local commit and connecting to the remote server, i received Git error: The remote end hung up unexpectedly

What could be causing this error?

You need to update this, v4 got ability to use onsuccess as params..

sample

Code:

var compID = "ListView";

var myComp = "/comps/defaultViews/defaultListView.waComponent";



        $$(compID).loadComponent({ 

                path: myComp, 

                userData: { myParameter: "something"},

        });

My solution is very buggy, event triggering twice and not sometimes

vegarringdal — Sun, 28 Apr 2013 13:03:09 GMT

For some reason my solution is very buggy

Some button clicks trigger twice, and when I reload a component, it does not trigger the "load" of that component.
it's very anoying :RpS_crying:

https://dl.dropboxusercontent.com/u/...20%2826%29.zip (removed)

Anyone have a clue whats going on?
UPDATE 29.04.2013:
ok, Ive figured out of the bugs.
The part with events triggering twice was my fault, had added to index.js files to the index html.

Webcompoents.
My listFooter/content footer does not work the next time I reload it because it's the same name for each class view.
Is this a bug?
Feel its weird we cant have same name on components located at different locations.
Could someone from team confirm it, is this to be expected or if it is a bug?
everything works fine if I use unique names on the webcomponents.

handle session expiration

Patrick.Poetschke — Sun, 28 Apr 2013 05:04:49 GMT

Since I'm using access control for classes (especially the new describe action, thanks again Laurent) I got problems when the session expires. When I then try to reload the page, the page isn't loaded because WAF throws an error requesting the $catalog. I even don't get to onLoad of the page to handle session expiration and redirect to the login page.
Is there an elegant solution for handling session errors before WAF stops execution?

BeautyTipMessage & Dialog

Hi all.

I'm trying to use bt to activate a tooltip, but I have a problem if the object is inside a dialog in modal way.
To activate message I have to move manually the dialog.

See the video:

This is the function:

Code:

WAF.Widget.prototype.setBeautyTipMessage = function (text){

        this.$domNode.bt(text, {

                offsetParent: $('body'),

                fill: "#9988ff",

                strokeStyle: "#B7B7B7",

                padding: "8px",

                spikeLength: 10,

                spikeGirth: 10,

                cornerRadius: 0,

                cssStyles: {color: "black", fontWeight: "normal", fontSize: "14px", fontFamily: "arial,san-serif"},

                width: "200px",

                positions: "top"} 

        );

}

Can someone help me to find a workaround?
Would be greatly appreciated

Dynamically assigning the datasource

North2Alaska — Sat, 27 Apr 2013 14:29:57 GMT

My main page consists of a navigation area and a component. I change the component based on the buttons selected in the navigation area. I load the component with a component that contains a tab view widget. In the second tab I display the details of a record in a container. In this container I also have a reference to another component. This component contains several buttons that will act on a record.

The organization looks something like this:

index.html
- Component (mainComp)
-- Loaded Component (projects.waComponent)
--- Tab View (projTabs)
---- Tab Container (projDetailsCont)
----- Container (projContDetails)
------ Component (recNavCompDetails)
------- Loaded Component (recNav.waComponent)
-------- Container (recNavCont)
--------- Image Buttons (recNavBtnXXXXX first, previous, next, last, cancel, remove, create, save)
Attachment 2647

What I would like to do is make these buttons work for a dynamically assigned datasource so that I could reuse the button set for another datasource on a different page.
Questions:
1) What is the best way to reference the buttons?
2) How do I assign the datasource to each button?
3) How do I assign the datasource action to each button?
4) How do I center the recNavCompDetails component in the Tab Container?

How to solve his problem - folders and subfolders

Jernz — Thu, 25 Apr 2013 23:19:41 GMT

Hello,

I am relatively new to Wakanda as well as web development, and I have a problem I would like to present.

Our clients are self-storage facilities. I want them to be able to log in using the address format www.domain.com/facilityname which takes them to a login page. When they log in they are directed to www.domain.com/faclityname/reportspage to access reports.
I have been reading up on httpRequestHandlers and this seems to be a solution, but at the moment I'm unclear how to use it exactly.
Can someone please give an example of how to return specific pages for these URLs? It would be dynamic.
I.e. if there are three facilities that can log in at
www.domain.com/123
www.domain.com/abc
www.domain.com/zyx

they all open a single login page. Then after they are authenticated they are directed to the main page, i.e.
www.domain.com/123/reportspage.
So this will become the "root" for them.
I hope this makes sense.

Can someone please point me in the right direction for doing this in Wakanda?

Async execution problems

lordwhiskey — Thu, 25 Apr 2013 15:13:01 GMT

Hi everybody,

i'm new to wakanda world and i'm training myself.

I've built a little application with a simply data model.

I'm trying to run this script behind a "onClick" event of a button.

Code:

                statistiche = ds.Stats.allEntities();

                        categorie = ds.Categoria.allEntities();

                        

                        statistiche.toArray("",{

                        'onSuccess':function(evento)

                        {

                                arrayStatistiche = evento.result;

                                var num = arrayStatistiche.length;

                                

                                for(i=0;i
                                {

                                        

                                        collezione = ds.Categoria.query("ID= :1",arrayStatistiche[i].linkCategoria);        

                                        //alert(arrayStatistiche[i].linkCategoria);

                                        //collezione = ds.Categoria.query("ID=1");        

                                        //debugger;

                                        collezione.toArray("",{

                                        'onSuccess':function(evt)

                                        {                        

                                                arrayCategorie=evt.result;

                                                indice=evt.userData;

                                                prova=prova+(arrayCategorie[0].Nome_Categoria+" - "+ String(arrayStatistiche[indice.index].counter));

                                        },userData:{index:i}

                                        });

                                        

                                        

                                }

                        }

                        });

My goal is to place in prova variable two strings, a name of a category and the number rapresenting how many items there are in that category.

Well, when i run this code what I obtain is that like this

"Category 1 - 1 Category 1 - 22"

even if the right result should be "Category 1 -1 Category 2 -22"

It seems not upgrading the array containing the name of category.

Another thing is that if I uncomment the row

Code:

//alert(arrayStatistiche[i].linkCategoria);

The program gets the right result. And this is suggesting some "timing problem" during asyn execution.

Am I right or I'm missing something?

Thanks

How to implement model relationships using a grid?

aikendev — Thu, 25 Apr 2013 00:06:30 GMT

Everyone,

Just starting with Wakanda and have hit an issue that I am struggling with.. Hopefully someone out there can point me in the right direction!

I have a few simple model (see attached), that defines three classes..

1. Order Class - Contains header information about a work order.
2. Item Class - Contains information about an item.
3. OrderItem Class - Contains information about the qty required/produced for a given item and order..

So the relationships are easy -

Order Class contains a 1->N relationship to OrderItem Class.
OrderItem Class contains a N->1 relationship to Item Class.
Item Class is freestanding..

Basically I have an order record that is related to one or more OrderItem records which has a "foreign key" to a single item record..

Now my trouble is I thought this would be easy! Just drop a grid, connect this to the Order Class (which works).. Drop another grid and drop the 1->N relationship to the OrderItem class.. and all would be well.. But alas NOT SO!

When I associate the 2nd grid I DO get a list of OrderItems entities, BUT the orderItemNumber (the "foreign key") to the OrderItem class is missing? If I create a new record in the grid then I am unable to enter the lineItemNumber. The field is missing..

I must be doing something basically wrong.. Anyone out there that can so me the error of my ways?

Thanks in advance,

Querying on date issues

HansA — Wed, 24 Apr 2013 20:13:30 GMT

Hello. I am wanting to query on date and I am confused why its not working.

This is my code:

Code:

today = formatter.formatDate(new Date());

var theLocationInventoryHistory = ds.LocationInventoryHistory.query('issueDate = :1', today);

The debugger shows the 'today' variable to be "04/24/13" which is correct, but the query path is being shown to be "LocationInventoryHistory.issueDate == 12/31/02 12:00 AM"}

Why is the query path "12/31/02" and not "04/24/13"? Thank you!

We use setTimeout to call a function at a regular base. (we use setTimeout by intention, but setInterval has the same problem)
The function is called several times, but then it stops.
Under Mac OSX it works fine as expected, but not under Windows (7 Ultimate), neither 64bit nor 32bit (also tested on different machine).

To reproduce this, I have attached a sample solution. Just start the server, open the debugger (or open the logs) and you should see a "beep"-string every second. In OSX it does, but in Windows the worker stops working... pretty lazy worker eh :RpS_wink:?

External Databases

leroy — Wed, 24 Apr 2013 13:31:57 GMT

Very new to wakanda so some things I only understand like a 5 year old.

I am trying to figure out what options are available to connect to external databases. Like many people I have apps that are using MySQL and MSSQL databases. I have been reading through the posts here trying to discern the options available.

I don't necessary want to import the data rather just do a query against the existing database. For example, a customer has a crm application that stores a client list in MSSQL (or it might be mySQL depending on the scenario). I would like to create an app with Wakanda that references that client list.

I see a new module for MySQL so the query listed above _I think_ is 'built-in' to Wakanda. What options are available to connect to a MSSQL database? (I saw one post about system workers + php) Is that the way to go? Create another application to handle the data interaction to SQL and return a json string? Seems like a big performance hit especially in light of how fast Wakanda seems to be.

Thanks.

Model : addAttribute & default value

avac2005 — Wed, 24 Apr 2013 11:03:31 GMT

Hi,

From Model API, when I am creating a new attritube with addAttitrbute command, there is no option for default value. How I will pass a default value for a specific database field ?

For example : City-> not null, default value:'Paris'

Solved Grids, Arrays and Components

lweidig — Tue, 23 Apr 2013 19:16:07 GMT

Can somebody provide me with a basic example showing an array being filled in code and then displaying in a grid. I can see the rows of the grid being added, but my data is never displayed. Also, say I create an Array in the datasources called myarray in code I can load myArray[0] with stuff and nothing shows. I can see that I have sources.myarray also exists. Then through both the array datasouce / grid into a component.

Guess I am just confused on getting these to interact properly. I can display stuff from my model in the grid no problem and all is happy.

Thanks!
