Hi,

      I'm trying to figure out and researching but all i find is not something i am looking for (or perhaps i need to look more). My problem is that the component i have in my context view isn't dynamically instantiated but is already there when loaded (view inside the context view), and with the code such as:
   
 // application context script at startup bootstrap
    mediatorMap.mapView( myCustomView, myCustomViewMediator );
     
it seems like myCustomView isn't being mediated because myCustomView loaded already prior to context initialize? In am aware that in flex the context should be instantialize during preinitialize event - but how do i do this in Flash? I am also aware of another way which is:
  var cv:myCustomView= new myCustomView();
    contextView.addChild(cv);

but then i have to adjust the coordinates of myCustomView programmatically (i.e. cv.x = 100; cv.y = 300) which i am trying to avoid where I can eyeball the layout position during design phase.

I hope my question make sense.
Thanks.

P.S. I'm a seasoned PureMVC user.

   if the instance is already on stage, just map the mediator as normal, and then mediate it manually

   as in

   mediatorMap.createMediator(thingOnStage);

   didn't work :-s

   // context onStartup

     mediatorMap.mapView( myCustomView, MyCustomMediator1);          
     mediatorMap.createMediator(Main(contextView).view1);
    super.startup();
   

   ---

   Where: view1 is of myCustomView class.

   i have a trace inside myCustomViewMediator1 like so: trace('myCustomMediator onRegister'); but is not firing. Is the Context right place to map the instance to it's Mediator?

   Hmmm that's weird, it works for me! You do override your Context's startup() method, right? (because your example says onStartup...)

   yeah ... are you using Flash IDE? I attached the source.

   Any chance that your [Inject] and [PostConstruct] metadata is getting left behind?

   That would prevent it from working as it should.

   If that's possible, the easiest way to verify that would be to create a dummy command, and map it to ContextEvent.STARTUP_COMPLETE, and inject a constant into it using mapValue, and then test for it on execute and throw an error to tell you whether it has or hasn't been received. Like this:

   // in your DummyInjectionTestCommand

   [Inject]
   public var confirmationOfInjection:String;

   ... function execute():void
   {
   if(confirmationOfInjection == null)
   {
   throw(new Error("The confirmation injection was not fulfilled"));
   }
   else
   {
   throw(new Error("Confirmation injection was: " + confirmationOfInjection));
   }

   }

   // in context startup

   mapValue(String, " confirming that injection is working just fine");

   commandMap.mapEvent(ContextEvent.STARTUP_COMPLETE, DummyInjectionTestCommand);

   yeah, that's my assumption as well but dont know the workaround at the moment ...

   Did you do the test?

   If you confirm that the injection isn't working then check out the FAQs for tips on getting injection working in CS4.

   Trace was:
   Error: Confirmation injection was: confirming that injection is working just fine

   it's working... so it's odd onRegister is not firing.

    Ok. found the culprit ... i am suppose to mediate the views inside command controller not in the context ...

    and instead of super.startup(); i should issue:
    commandMap.mapEvent(ContextEvent.STARTUP, StartupCommand, ContextEvent, true); dispatchEvent(new ContextEvent(ContextEvent.STARTUP));
