When the revert option is selected, what changes occur to the underlying data supporting the outline view? Once the window/sheet is dismissed, it looks like the main/document window is asked to redraw its contents and the problem occurs there (redrawing the outline view). That probably occurs before the -windowWillClose: call takes place. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
