I've got a simple detail view backed by an NSArrayController. The view views
the NSArrayController's selection. The NSArrayController manages an array of
dictionaries, all very simple.
I've implemented validateValue:... and it's being called when I want it to
be (thanks to "validates immediately"), except on this one occasion:
The user can create a new object - the button calls add:, and I've
overridden newObject:. However, this new object is deliberately invalid;
some fields are blank, but the user must fill them in before leaving and
moving to another selection. That's the intention, anyway. The problem is
that that is not happening; the user can press the selectPrevious: button
without doing any editing, and no validation takes place. Obviously that's
because the user didn't do any editing!
How can I fool the system into thinking the user has done some editing in
every field, so that when the user leaves this selection for another, every
field will be validated? m.
