This is a little bit clearer, but still to vague to be of much use. The short answer is that it sounds like you have 2 mutable arrays underlying all of this. After you've checked the item removal in the debugger, you should check in the debugger again at save time that it's the *same* array you're saving, rather than a duplicate that hasn't had the item removed. I have no idea what "bound via an NSObject proxy in that same XIB to the same NSMutableArray as controller A" means. I'm also not sure, when you say "bound", you are always referring to an actual binding, or sometimes to an outlet connection. To solve this, we need to to know all of the bindings, including (for each one): the object that's bound from; its location (in nib or created programmatically); the binding name; the object that it's bound to; *its* location; the property key that its bound to. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
