I just changed that, it's now called from some other places as well
(drag/drop support). I think it used to be called also from the drag/
drop support of the form, at least at some point.

I'm not sure which alert you're alluding to here?

I think that when we revert changes or prevent committing we need to
show an alert.

I'm not sure about the different notifications that go on and the
order of them. Also note that when the app terminates windows are
closed without going through notifications.
Also when the fields are changed they have to stop editing, otherwise
the UI is in an inconsistent state wrt to the data.
