NSObjectController and subclasses ignore any options you provide in -addObserver:forKeyPath:options:context:. This means you can't get "prior" KVO notifications, and therefore can't know the value you're changing *from* in response to a KVO notification. Also, IIRC this means you cannot use +keyPathsAffectingValueForKey: to auto-observe through an NS*Controller. We no longer use any NSObjectController subclasses in our apps, and will not until Apple fixes these issues. --Kyle Sluder (sent from the road)_______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
