Is this a known problem?
My thinking is _setSuperview: seems somewhat a surprising place to crash. I’m hazarding a guess that the accessory view is not a fresh one, and still has a reference to its previous superview. Apple’s code doesn’t expect that situation, and finds the pointer to the previous superview to be invalid perhaps. This is Apple’s bug, but if my guess is correct, you could probably work around it by manually _removing_ your accessory view from NSSavePanel once the panel returns, rather than leaving semi-attached there. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
