Hi Faisal, I think the problem is in the way you are adding the window. Since you are just using addChild(), the window is never assigned a windowManager and I think that is what is null. If you say mdic.windowManager.add( window ), it will addChild() for you and also set the windowManager property correctly. Try that and I think you will be all set.
That said, I think its completely reasonable to expect things to work the way you had them coded. I am going to look at overriding addChild() in MDICanvas to support that workflow so look for that in a future release.
