I'm having some troubles with data binding and a named event generated
by a custom non-visual component. What I'm trying to do is have a
property (say, 'data') which, when it changes, triggers the usual
data-binding updates, but also fires an event that can be listened to
in the MXML. For example:
<foo:MyClass id="thingy" dataChanged="Alert.show('hi mom');"/>
<mx:Label text={thingy.data}"/>
I can't seem to meet both of these requirements without throwing two
separate events. Is this what I should expect?
When I do this:
[Event(name="dataChanged")]
public class MyClass {
[Bindable(name="dataChanged")]
public function set data(data:Object):void {
this._data = data;
dispatchEvent( new Event("dataChanged") );
..then the data binding doesn't work. (The label text doesn't get
updated.) It seems I have to resort to vanilla data binding (with no
event name), and in addition throw a 'dataChanged' event of my own.
[Event(name="dataChanged")]
public class MyClass {
[Bindable]
public function set data(data:Object):void {
this._data = data;
dispatchEvent( new Event("dataChanged") );
Am I missing something?
