Actionscript 3 :: Flex 4 XML Attribute Binding Not Working?

May 13, 2011

For some reason this seems to no longer work in flex 4, it used to work in flex 3.[code]I am setting the xmlTitle variable outside of the component:<local:Comp xmlTitle="Some Title" />I have tried with getter / setters...etc. It just does NOT update when changing, it shows the default value and never changes. Is this a known new bug in flex 4?

Flex :: Data Binding Not Working

May 3, 2010

I'm having some troubles with binding data. I have an application that contains a viewstack of components. Let's say I have comp1, comp2 and comp3 inside the viewstack. Each component, has its own data class --> comp1Data.as, comp2Data.as and comp3Data.as. All values in each component are binded to the corresponding data in it's data object.

A click in a control in comp1 leads to comp3, the same goes for comp2. Clicking a control in comp2 leads to comp3. When going from comp1 to comp3, comp3Data.as is initialized and and comp3 displays the binded values. When going from comp2 to comp3, comp3Data.as is also initialized but the binded values are not displayed...

ActionScript 3.0 :: XML Parsing Not Working When Attribute Has A : In The Attribute Name?

May 13, 2009

I am having trouble parsing some xml that has a few attribute names with : characters in them. The compiler is not throwing any errors and when I trace my complete xml object out it is all there, however when I try to trace out any element or node it keeps comming up undefined. I removed the attribute names with : characters in them and everything works fine. I cant seem to target the attributes either to delete them.

Actionscript :: Disable Warning (especially Binding Warnings) In Console In Flex (eclipse With Flex Plugin)?

Nov 10, 2010

I did suppress warnings in flex compiler using "-show-binding-warnings=false". But what I am interested to achieve is to suppress run time warnings (especially binding warnings - since I am getting data in model mostly in XML structures and it is fine for me if its unable to bind to its nested child nodes) in console (I am working on flex on Eclipse with the flex plug in). Is there a way to achieve it?

Flex :: Conditional Data Binding?

Oct 8, 2009

first one shows playheadtime of videodisplay and another is also used for same purpose. the difference is that when we are in add mode(decided from a flag variable) both should show current playheadtime using binding. but when we are in edit mode(again decided from flag) the latter label should remain static, to be more specific, the value retrived from database.how can I do that using actionscript. I tried ChangeWathcer but I found it a bit tricky. Is there any other simpler way or am I missing something. following is my code.

private function init():void

Flex :: Binding Key / Value Pairs Loaded From Xml

Mar 12, 2010

I want to load key/values configuration pairs stored in XML file. To bind a collection of data i know i need to use the ArrayList class, but the problem is that i want to be able to bind the loaded values using their corresponding keys and not by their indexes in the ArrayList object. For example i want to be able to do this :

[Code]...

So the question is how to bind the key/value pairs loaded form XML. I don't want to go manually set variables, i want to bind them so when they are loaded the are set automatically. Did anyone had to do something like that ?

Flex :: Binding Applies Only To One ArrayCollection?

Apr 15, 2010

I have a datagrid that gets its data from a webservice.When data from the webservice is retrived it calls the following function:

private function onListReg():void
{
arrRegOld = WSAutoreg.list.lastResult as ArrayCollection;
arrReg = WSAutoreg.list.lastResult as ArrayCollection;

[code].....

The intent is when I hit a update button, it compares arrRegOld with arrReg and see if any values have changes. The problem is whenever I change values on the Datagrid it changes on both the dataProvider and on both ArrayCollections.What should I do so that the binding applies only to one ArrayCollection?

Flex :: Binding To Arraycollection Does Not Work?

May 23, 2010

I am using flex SDK 3.5. I have model.as and in it i have an ArrayCollection (name it arr_mod) which is Bindable.

From my mxml i link to this arr_mod in three places:
1) in DataGrid i set dataprovider={arr_mode} ...

2) in Button i add new item to the arr_mod this way: mx:Button .. click = "{arr_mod.addItem(new Item)}"

3) in textBox i want to add mx:TextBox text="{mySpecialCounterFunc(arr_mod)}"
note that in the Script of mxml arr_mod is Bindable as well as in the class definition in model.as

The problem is, that when clicking on button, mySpecialCounterFunc is not called! it should be called, since i use {} and this should listen to changes in arr_mod (a change that was made in the button should cause a new item to be added.. and than the listener to respond). While The DataGrid is updated correctly! By the way, if i change arr_mod to simple String or Int it works.. i.e. mySpecialCounterFunc is called Why??

Flex :: Binding ArrayCollections Of Arrays?

Jul 17, 2010

I've been kinda stuck in trying to organize data and bind them to a Repeater in one my applications.What I did at first, was to save an array of arrays, so that I could've accessed any value very easily. But then I realized that I needed to bind them to a Repeater, so I had to switch to an ArrayCollection of arrays. But the Binding issues weren't solved, since there are still arrays (not bindable) inside the ArrayCollection.Below an example of what I want to do:

<mx:Script>
<![CDATA[
import mx.collections.ArrayCollection;
[Bindable] public var arr:ArrayCollection = new ArrayCollection(

[code]....

the traces show that the array size changes, but the repeater doesn't update.

Flex :: Binding Component To Class Function

Sep 5, 2009

I have several components where I want to enable buttons based on passing a username to a function. I want to dynamically bind the "enabled" property on a button so that if the "somethingChanged" event fires, a button may become enabled or disabled. But, I'm not sure where to fire the "somethingChanged" event. It's possible that I may need to fire the "somethingChanged" event from several places in the application. Is this possible with a bound static function?

EventManager.as
public class EventManager():void {
[Bindable(event="somethingChanged")]
public static function hasAccess(myVal:String):Boolean {

Flex :: Data Binding With A Value Inside A Component ?

Mar 30, 2010

I'm using Flex with Cairngorm framework.I have a custom component which I create like this:

<components:FriendSearchPaginator id="searchResultsPaginator"
paginationElement="{_model.findFriendsPaginationElement}"
visible="{_model.friendsSearchResultsPaginatorVisible}" />

Where the findFriendsPaginationElement is inside the model locator:

public var
[Bindable]
findFriendsPaginationElement:PaginationElement = new PaginationElement();

Inside the custom component I have button that uses a property of findFriendsPaginationElement object:

<s:Button id="previousButton"
label=" prev "
click="paginateSearchResults(false)"
enabled="{_model.findFriendsPaginationElement.more_previous}"/>

But I get a warning from Flex that the binding wouldn't work that way and it doesn't. It works the first time I load up the component but every time I change findFriendsPaginationElement it doesn't reflect on the component. Do you know how I can go about doing this? (making changing a value in the binding variable changes the status of an element inside a component?)

Flex :: Binding ArrayCollection Result To DataGrid

Jun 29, 2010

I am trying to bind an ArrayCollection result coming in from the server to my DataGrid
created dynamically in AS. The result data is not getting Displayed in the Grid.
var dg:DataGrid = new DataGrid();
dg.width=650;
dg.dataProvider=someArrayCollfromServer;

I am adding the dgColumn as runtime based on some data from a XML and it is the same as defined in below static format. But if I use the same code and create the DataGrid as a Flex Component as below, it works fine.
<mx:DataGrid id="dg" width="100%" height="100%" dataProvider="{someArrayCollfromServer}">
<mx:columns>
<mx:DataGridColumn dataField="Value" headerText="Value"/>
<mx:DataGridColumn dataField="Code" headerText="Code" />
</mx:columns>
</mx:DataGrid>

This works fine. Is there some functionality or implementation different as far as DataGrid is concerned in Flex and AS.

Flex :: Two Way Data Binding In AS Causes Stack Overflow

Jul 21, 2010

I'm binding two AutoCompleteModified objects to one another; meaning you type in one and it selects the correct object in the other. It works fine when I define it in MXML: However, a user can add a new row to a Grid and then I set up the binding and objects via actionscript and it gives an 'undefined' error:
ChangeWatcher line 427/wrapHandler.

var innerHBox:HBox = new HBox();
var dtc_acm:AutoCompleteModified = new AutoCompleteModified();
dtc_acm.dataProvider = data2;
dtc_acm.labelField = 'id';
var cp_acm:AutoCompleteModified = new AutoCompleteModified();
[Code] .....

If I only keep it 1-way binding then it works fine. But both throw this error. Is there something about not only doing it 2-way in actionscript, but adding components that aren't on the stage yet?

Sql :: Flex 4: Binding Label To Dataprovider (SQLite)?

I am trying to display records from an SQLite database within my Flex mobile application. I have the input form saving data correctly to the database, and I have a datagrid that is outputting the records (so I can confirm everything looks good). However, my problem is making the data readable.
