-awakeFromNib is called whenever the receiver is awoken from a nib, or is used as the owner of a nib that is instantiated. Therefore, it may be called more than once on any given object.
What's happening:
Document system is preparing an accessory view for the save panel, probably so it can offer a popup with a few different document types. The view is loaded from a nib, by the document, and so calls -awakeFromNib.
Anyway, the fix:
Don't use -awakeFromNib. -windowControllerDidLoadNib: sounds like it's a better match for your needs.
Mike.
