If I create an object like so:
class Foo {
[Bindable] public var property: String;
}
The class Foo has an implicit event dispatcher to handle property change events. How can I access that without making Foo explicitly extend EventDispatcher?

I've got a component called Box.as that has following two properties, and have their getters & setters defined:
private var _busy:Boolean;
private var _errorMessage:String;
In MXML that uses this component I define it like this:
<components:Box skinClass="skins.components.BoxSkin"
busy="{presenter.boxBusy}"
errorMessage="{presenter.boxErrorMessage}"/>
Where presenter variable is defined here in MXML and a Presenter class has boxBusy and boxErrorMessage variables defined as bindable property change events:
[Bindable(event="propertyChange")]
function get boxBusy():Boolean;
function set boxBusy(value:Boolean):void;
[Code]....
PROBLEM is that whenever I change boxErrorMessage for the presenter, I see the affect in MXML but nothing happens at all when I change boxBusy. Is there something extra I need to do with boolean variable?
I have inherited an Adobe AIR application, and am attempting to debug it through Flash Builder 4.5. Within Flash Builder, when I look at one of the MXML files, I see warnings for each use of the [Bindable] tag:[code]And there are no missing semi-colons on the lines preceding each warning as per the suggestion in this blog post.The project is configured to use Flex SDK 3.6.Additionally the file will not load in the designer, with this warning:Design mode: Error during component layout. Choose Design > Refresh to refresh design mode.At runtime I am seeing a blank window - which I assume is the result of the bindings not being triggered. Is this tag not available in Flex SDK 3.6?

In my flex app I have a public bindable property.I want it so that every time the value of that property changes, a function gets triggered. I tried using ChangeWatchers, but it seems those only apply to built-in components like a text box change.i would like to do that same behavior with a property that changes at runtime.
View 4 RepliesI have a class like this. Property "isPag" is based on filed "ecboardid", I found that when ecboardid is changed, UI controls seem not be able to detect that "isPag" is also changed. So, how to make a property like this bindable?[code]...

I have an AS3 ResultEvent Object and this object has several propeties which can be accessed by this like:event.result.name or event.result.age and, I have this String variable: eventProperty:String that contains "name" or "age" How do I access to event.result. with the variable?

My Combobox is not alway updating when I update the ArrayCollection.[code]...
the first time it updates the combobox fine and sometimes it works the 2nd, 3rd, etc time is might update the combo box. After it stops updating the combobox, it never does until I restart the app. I have verified that the ArrayCollection is updated via the debug data, it is just the combobox is not updating the display.
I have Class1 with a read-only bindable property called age:
public class Class1 {
private var _age:int;
[Bindable(event="ageChanged"]
[Code]....
Of course the [Bindable] tag there doesn't make sense. But how can I achieve the same effect?
I believe I can dispatch some sort of ageChanged event from Class2 up to Class1 and then have an event handler in Class1 dispatch another local ageChanged event to which I bind Class2's age property.
I have a Number variable, named isConflict, whose value is passed in from a parent. I would like to put a ChangeWatcher on this item so that a function named changeBGColor will run whenever the value is changed. Within my creationComplete function of init, i have the following:
var isConflictWatch:ChangeWatcher = BindingUtils.bindSetter(changeBGColor, this, "isConflictChain");
I am just just curious as to whether the [Bindable] metadata tag in ActionScript 3 can only be used within the Flex framework, or can it be used in "regular" ActionScript projects where Flex isn't used?

I'm programming a little tank game (Check the attachment). The main class for tank is game.serovkonstantin.tanks.Tank.as and there are also 2 subclasses for now: Abrams and T90 which extend Tank. In my game.serovkonstantin folder I have a custom event (TankEvent), and the only event type inside of it which is TANK_INACTIVE.
I've added an event listener for MouseEvent.CLICK to each of the tank instances (inside Tank.as) which works just fine. When I add any of the tank instance onto the stage and click it, it traces the tank's name just like I wanted whether it's Abrams or T-90 depending on what tank I clicked. But the problem is that when I click a tank I also want it to dispatch my TankEvent.TANK_INACTIVE. The main stage has a listener for this event, so I expected it to catch the event and trace some phrase, but nothing happens I don't know whether it doesn't dispatch my event or doesn't catch it.
========
if you're interested why I need to dispatch this event, well,I suppose it will help my game know what tank to move when I click somewhere on the stage, and what tank(s) should be inactive,event it they all of the same type. I mean if I click one of the tanks it accepts all the controls while the other should be inactive
ActionScript allows you to mark a variable as [Bindable], causing any changes to that variable to have immediate effect all over your application.How would you implement this feature in your favourite programming language?

I am developing an application with Flex for the GUI and Restlet for the webservices. I have a strange problem. I put my XML as a property on a generic object, and send it as part of a POST request. But in the Restlet webservice, this XML is irretrievable. How do I retrieve it? I tried initialising the received Representation object to a DomRepresentation, but thats not working. If I put the received Representation object into a Form object, then getFirstValue is returning that XML as a string! I noticed that the contentType of the HTTPService was application/www-form-encoded so I set it to application/xml and its not helping either. I use restlet 2.0m6 and here is the code snippet that I use -

So I have two classes talking to each other with EventDispatcher. One is a thumbnail of an image, and when it's clicked, it sends an event to the other class to display the full size version. I'm using a MovieClipLoader instance to load the full version (and the thumbnail).
Here's how it's sending the event from the thumbnail class:
Code:
private function initButton () {
this.loadMe.onPress = function () {
this._parent.sendEvent();
}
[Code]....
The problem I'm having is it loads the full size version ONCE. After that, it no longer receives the event. The ("event received") trace no longer comes through. But the ("send event") trace continues to work.
The other weird part is if I comment out the loadClip, then the events come through just fine on both sides. But it's like after it loads an image once, it quits responding to that event ('onPhotoSelected'). Is there some kind of mis-communication between the events of the MovieClipLoader and my custom event or something?
I have a situation where I need to update a DropDownList's dataProvider and selectedItem in a specific order. See the following code ...
<s:DropDownList id="dropDownList"
dataProvider="{someDataProvider}"
selectedItem="{someSelectedItem}" />
In my case, some user interaction produces new values for the bindable variables "someDataProvider", and "someSelectedItem". However, when flex renders the DropDownList, the control's selected value is empty.
The reason for this is that the DropDownList's "selectedItem" property gets bound before the "dataProvider" property. The "dataProvider" needs to be bound first for "selectedItem" to be valid, this is because the new "selectedItem" points into the new "dataProvider".
what is the best practice for updating bindable properties in a specific order? I've come up with a few ways (e.g. using a valueCommit handler), but I wanted to see what the community had to say.
I have the following code:
<fx:Script>
<![CDATA[
import shared.GlobalsManager;

I have two movieclips: MovieClip X and MovieClip Y.
MovieClip Y is nested inside of MovieClip X. MovieClip Y contains buttons with listeners attached to them. These listeners call a method
Code:
buttonClickedHandler();
inside of buttonClickedHandler();... dispatchEvent() is called to dispatch a custom event that bubbles up to MovieClip X. This chain of events works as intended, I can set up a listener in MovieClip X for the custom event and everything is fine...
The problem comes when I try to invoke a dispatch on a button in MovieClip Y without actually physically clicking it. If i call
Code:
ButtonA.dispatchEvent(new MouseEvent(MouseEvent.click));
the listener for the button click event will fire properly, and if i trace the dispatchEvent of the custom event, it returns true meaning the event was dispatched successfully. But in MovieClip X... the listener for that custom event is never fired, its as if the custom even is not bubbling.
I am working in Flex Builder 3 and I am trying to figure out this error. The error console reads "Access of undefined property EVENT." I am not understanding why this error is showing when I have already imported flash.events.Event. Flex is not recognizing with even the hinting helper pop up that appears when I type the addEventListener(It should appear after the opening parenthesis right? Also, I cleaned the targets and still no luck.

How do i create a trace that can detect if an event dispatcher is dispatching an event?....my problem is i've created a custom event that is not being dispatched i use this custom event in other applications and have verified that the code is correct I'm not getting any errors neither it just dies silently
View 1 Repliesthere are 2 functions in my code that dispatch a TweenEvent. each function dispatches the same tween and adds the same TweenEvent.MOTION_FINISH event listener. however, the event listening function must act according to which function dispatched the event. is it possible to get the function of the event dispatcher from the event listener? i could use a flag to make this work if there are no other elegant solutions.

I created a class that extends the displayObject3d and added an Event dispatcher like bellow:
Code:
package {
import flash.display.Sprite;
import flash.display.Stage;
import flash.events.Event;
[code]....
but unfortunately the event never dispatches.
If I have an event listener which picks up an event, how can I remove the event dispatcher? I would be looking for something like this.
Code:
addEventListener(MouseEvent.CLICK, onClick, true);
function onClick(event:MouseEvent):void
{
event.target = null;
}
I had to reformat my question because I realized I was using incorrect flex method. But still a similar issue occurs:
private function passForm():void {
PopUpManager.addPopUp(passTitleWindow, this, true);
PopUpManager.centerPopUp(passTitleWindow);
[code]....
I click and popup does not display.
