If you know the name of the event generated for [Bindable] you can
simply put multiple bindable statements on the fullName property:
[Bindable(event="firstNameChanged")]
[Bindable(event="lastNameChanged")]
Public function get fullName():String {...
I don't remember if we document what the event naming pattern will be.

Subject: [flexcoders] Feature request: dependant bindings meta-data
Hi Adobe Team,
Is this the right forum to talk about Flex Builder features? I have
often found myself in situations where it would be very handy to say
something like this.
[Bindable] public var firstName:String;
[Bindable] public var lastName:String;
[Bindable(basedOn='firstName,lastName')]
public function get fullName ():String {
return firstName + ' ' + lastName;
}
The idea being that when a binding for firstName or lastName changes,
the dependant binding fullName will also get fired. The only way I know
to do this with the current tools is:
private var _firstName:String;
private var _lastName:String;
[Bindable] public function get firstName():String {
return _firstName;
}
public function set firstName(str:String):void {
_firstName = str;
dispatchEvent(new PropertyChangeEvent('fullNameChanged');
}
[Bindable] public function get lastName():String {
return _lastName;
}
public function set lastName(str:String):void {
_lastName = str;
dispatchEvent(new PropertyChangeEvent('fullNameChanged');
}
[Bindable(event='fullNameChanged')]
public function get fullName ():String {
return firstName + ' ' + lastName;
}
Which is obviously less expressive. It would be great to have a kind of
'based on' meta-data for bindings as in my example. Or is there a way to
do this already that I don't know about?
Many thanks,
Lach
