It is not possible to retroactively change the designated initializers for a class. The designated initializer pattern requires subclasses to cooperate by overriding and calling particular initializers. Changing the designated initializers for a class like NSDocument would break all of its existing subclasses. -- Greg Parker gpar...@apple.com <mailto:gpar...@apple.com> Runtime Wrangler _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
