NSUndoManager for loaded documents

Subject: NSUndoManager for loaded documents

Hello all,

Is there something special I need to do so that my NSDocument derivative's "undoManager" method will return an NSUndoManager for documents loaded from disk..?  When I create a new document, my undo functionality works, but when I load a document from disk, I get "nil" back.  Even when I override hasUndoManager to return YES (the message is never received) or do a setHasUndoManager:YES in my init.

Thanks,
Sander_______________________________________________
