Hi, I imagine that at this time you solved your problem, but i found your post.
I had the same problem with a simple app. The problem is that the app doesn't know your VO (Value Object) and for that reason flash player marks "ClassCastException"; for solving you have to declare a var with your VO at your flex app: <mx:Script> private var item:Item; </mx:Script> That's all.
