I've got the same error and cant determine why.
It seems it has to with this line in the DragManager;
private static var impl:IDragManager =
Singleton
.getInstance("mx.managers::IDragManager") as IDragManager;
From what i can see FlexModuleFactory.docFrameHandler() is never
getting called from within the most recently loaded module
