Below is my code for popup, in my project, I have a problem to register
mediator, I try like this :: facade.registerMediator(new
InfoWindowFriendDetailsMediator(InfoWindowFriendDetails)); ::
Problem happened when I register events on my popup component controls, I get
null here and application crash. I don't know how to register mediator?

override public function onRegister():void
{
friendDetailsInfoWindow.btnCloseInfoWindowFriendDetails.addEventListener(MouseEvent.CLICK,
onCloseClick);
}
