If you find when developing in 10.7 that you get a versions menu with a NSMenuItem as one of the items, it might be worth checking to see whether you’re correctly using validateMenuItem:
This problem may happen if you return YES from validateMenuItem in a NSDocument subclass for menu items that you don’t actually control. (If you just return YES as a default for example)
If instead you return
You should get the correct “Revert to Last Saved Version” menu item
I ran into this when I was doing testing on 10.7 and although documentation clearly states that you must call the super method in validateMenuItem: , it wasn’t immediately obvious to me what was causing the problem.
Hope this helps if you have the same problem.
Edit: This may have been fixed in OS X
