Nono, when streaming an inherited form, the IDE provides the ancestor
instance when the streaming starts, because it calls writedescendent.

When you have a frame inside a form IDE, the IDE cannot provide the 
ancestor of the frame: the streaming code must look for the original 
instance of the frame by itself. My guess is that this is done by 
setting the OnFindAncestor callback ?
