I'm using a master/detail view in my application. If the user select another row in the master table and the detail has been modified, I want to present an alert to save, cancel or return to detail.
Back to the original question, I always thought that the desired behavior in this case would be to simply set the change in the data model without asking. You mentioned "save". Indeed, I would not "save" in the sense of saveDocument:. But like Graham said, a table entry is "cheap" [in user effort] to restore the old value if it was a mistake. And the proper, easy way for the user to restore it would be -- drum roll -- Undo -- cowbell :)
