I tried your suggestion of doing AcceptChanges before the RejectChanges and it actually works, but when I navigate to a different SCHOOL and then back the Undo doesn't work.

What I'm going to do is when they navigate to a different SCHOOL I'll query for any HasChanges and prompt for a save, undo, or cancel.

Thanks for your help!
