Having sorted out the problem that occurred when I closed files, I am now back to the "save as" issue (I was hoping that the two problems were related, but apparently not). I have reverted to using a stock standard NSManagedObjectContext I still haven't a clue where to look to debug this. Running it normally gives the following error:
