I added a new Modal window in an existing form.
By error, I changed the nameif thie new item to the same name as another item. I received an error message saying it is not correct, but then name has been changed.
I now have two items with the same key.
When I then tried to change teh name of either the new item or the existing one, I received an error message saying "property can' tbe change outside a transaction".
I closed VS and restarted it. Now when I try to change the name, I get a duplicate key error.
If I try to delete one of the item with duplicate key, VS crashes.
