RE: [flexcoders] metadata tags and events
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.

RE: [flexcoders] metadata tags and events
Cheers, I'd already tried what you'd suggested below and for whatever
reason it is still not updating the model.
I did see this in the standard DateField.as class
[DefaultBindingProperty(source=selectedDate,
destination=selectedDate)]
[DefaultTriggerEvent(change)]
[RequiresDataBinding(true)]
I think it's just down to the way that the custom component is using the
sets and gets and some weird flex magic. I've ended up doing the
following as a work around.
myCustomComponents:CustomComponent id=DoB change={updateModel( )}/
And whenever the change event is fired, I can pick it up here, although
I can't get any other bindings to pick up the event. The updateModel()
just gets selected date and puts that into a holder date variable which
the model binds to.
I've had a look at
http://livedocs.adobe.com/flex/201/html/wwhelp/wwhimpl/common/html/wwhel
p.htm?context=LiveDocs_Book_Partsfile=metadata_141_01.html and it's not
exactly a full list. Hm.
Bah there are times when the documentation for using flex is just
rubbish. Not to mention the search facility of livedocs doesn't seem to
be well indexed or something.

RE: [flexcoders] metadata tags and events
I dont think you need to do that much, perhaps you might be missing the event
declaration at the top of the class?
[Event(name=change, type=flash.events.Event)]
public class MyClass {

I don't usually ever suggest anyone go to a sys-con site, the thought of it
