In an xBase world I do this by using a field in a 1 record table.
Put your exception handling around the attempt to edit the record and
it works a treat.
Go the extra step and inherit a table component, add properties for
the table and field with the generator value, and a third one for the
field in this table that is to receive the new value. Add some extra
functionality to the "BeforePost" event that only fires when
posting an insert and you are done!
Works for me.
