Thanks for the information. I am in the process of moving what I can
to typed classes. Unfortunately that data comes from our server
component and it will take a while before our Java guy can get to it
on his end.
One last question. I have a custom class, extends EventDispatcher,
declared as [Bindable]. It has a read-only "status" property. I
have tried binding things to it like:
<mx:Text text="{myCustomObj.status}"/>
In the case above, I cannot get the text to update when the object
updates. Do I need the class to dispatch a specific event to trigger
the binding to update?
Thanks
Dominic
