In my table delegate I implement: - (BOOL)control:(NSControl *)control textShouldEndEditing:(NSText *)fieldEditor { if ([[fieldEditor string] length] == 0) return NO; // don't allow empty names else return YES; } This works when editing a cell in a table row when I press return If I change this to: - (BOOL)control:(NSControl *)control textShouldEndEditing:(NSText *)fieldEditor { return NO; } And start an edit session, if addObject is called on the ArrayCOntroller feeding the tableView, the cell edit session ends without this method ever being called. However: - (void)controlTextDidEndEditing:(NSNotification *)obj IS called. How can I prevent the edit session from ending when adding items to the array controller feeding the table view? _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
