Surely this is a job for the debugger. Set a breakpoint in 'validateUserInterfaceItem:' and watch what happens. It could be something as simple as testing for '@selector (delete)' instead of '@selector (delete:)', but you should be able to debug this problem in a shorter time than it took you to write your original post. :)
