Hi Ryan,
Tracy is kind enough to consistently answer many questions on this list.
Let me jump in here to help out. In answer to your original question:
Can I write to something a tab if it is now displayed yet in flex???
No, you can not reference an object that has not been instantiated yet.
TabNavigators and other navigator containers (Accordion, ViewStack...),
only instantiate the objects in the first child c0ntainer initially.
While your problem may be solved by using creationPolicy="all", Tracy's
advise is sage; since this will lead to performance degradation and
negate deferred instantiation.
The preferred method, very typical when using MVC, is to cast the result
of the service call to a bindable value object (VO) that resides in the
ModelLocator. Then bind {} the properties of the VO to the appropriate
controls.
So, instead of:
companyname = obj.companyname;
You would have something like:
<mx:TextInput id="companyname" text="{ myModel.myObjVO.companyname }"/>
This way, when the control is instantiated, the binding mechanism will
get the data; instead of trying to populate the text before the control
is created.
