Hello,
I have a small application that has a custom class used as the model
object of an NSArrayController object driving a NSTableView control. I
would like to be able to validate new values before they are applied to
the model, to filter things like negative numbers for array indexes or
other such kind of validation.
What is the proper way to do this in the controller layer model?
