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_Parts&file=metadata_141_01.html and it's not
exactly a full list. Hmmmmm.
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.

Just seen the email from Daniel F, cheers for that link, I'm currently
trying to ask adobe's gold (plated & somewhat tarnished) support and if
they get back to me I'll let you know what the extra tags do.
Thanks K.

Subject: 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.
