in order to tell other classes your object is bindable, it has to have this
metatag:
[Bindable("change")]
public function get text():void {
....
}
then somewhere is your component once the text field data is set, broadcast the
change event like so:
dispatchEvent( new Event("change") );

Subject: [flexcoders] metadata tags and events
Does anyone have information on the various metadata tags that can be used in
flex. I've been going through some of the source files to find out a way of
getting my custom component to tell a model to update itself.
Some of the tags I've seen that I don't know what they do are
[DataBindingInfo]
[DefaultBindingProperty]
[DefaultTriggerEvent]
I've seen others but I won't to list everything here.
I've searched Livedocs and I can't find somewhere where all the tags with
explanations are listed.
Also if someone knows about models being updated can you advise on the below
problem
If my model is
<mx:Model id="requiredFields">
<theForm>
<all>
<name> { name.text
} </name>
<birth> {
DoB.selectedDate }</birth>
</all>
</theForm>
</mx:Model>
<myValidator:FormValidator id="formValidator" source="{requiredFields}"
property="all"/>
When I call the validator the information it gets from the model is
the text from the text input which is updated everytime the user changes the
said text input, but the date comes from a custom date entry component and the
model doesn't get the latest date from the component. It would seem like the
binding isn't working or my custom component isn't firing of the required
events for the model to update itself when the user changes the date.
I've tried getting my custom component to fire of the following events
[Event(name="change", type="flash.events.Event")]
[Event(name="valueCommit", type="mx.events.FlexEvent")]
As well as making the getter function for selectedDate [Bindable], but the
model still doesn't pick up on any changes after the component has been
initialised.
Cheers for any info.
Kenneth.
