OK,I'll try this way! Thank you Cliff.

Hi,guys

now i have a question in programming.

so normally i register a MediatorClass in startCommand  like this:

:

var app:mainApp = notification.getBody() as mainApp ;
                        facade.registerMediator(new ApplicationMediator(app));
                        facade.registerMediator(new LoginMediator(app.Login));
but how to register a MediatorClass for a ViewCompontent what added to App stage in runtime?

like this compontent in mxml:

:

in my application.mxml script...

var myChatPanel:ChatPanel = new ChatPanel();
addChild(myChatPanel);


how can i register MediatorClass for this UIcompontent...

that's all ~~
