Issue getting viewState's selected child's id in flex 4

Question

I'm transitioning a flex 3 application to flex 4. There was AS code in the flex 3 app that worked:

var myCurrentSelectedChild:String = myViewStack.selectedChild.id;

Now, in flash builder and flex 4.5, it throws the error - "-1119: Access of possibly undefined property id through a reference with static type mx.core:INavigatorContent". I'm trying to get the viewStack's selected child's id.

try to cast the myViewStack.selectedChild to some displayObject type. core:INavigatorContent has no ID property. So use (myViewStack.selectedChild as DisplayObject).id — Adrian Pirvulescu, May 27 '11 at 08:29
@TiMeister DisplayObject doesn't have ID property but Container does so used (myViewStack.selectedChild as Container).id and it works. Thanks — Steven, May 27 '11 at 15:15

So use:

(myViewStack.selectedChild as Container).id
