You should make the trigger only assign a value from a generator if the
NEW.COLVAL IS NULL and then in IBO put a setting in the GeneratorLinks tab
so that it will grab a value from the generator upon going into insert
state. Keep in mind if you cancel the insert or if it otherwise fails that
generator value is lost. There is a whole TI sheet dedicated to generating a
contiguous series of numbers on the web-site if you need that.
