If you issue a refresh after you insert a row and you fill the generator in
a trigger instead
of leaving ibo filling it, ibo would not know which is the PK of the new
row inserted.
I think this is the most important reason why you should use generatorlink
instead of managing
it in a trigger.
But if you don't need to be syncronized with the DB when you insert (such
as when you import data)
then the faster thing is to implement generators using triggers.
Usually I use in my trigger this syntax:
IF ( new.ID_TEST IS NULL ) then

so I am able to use both solutions basing upon my specific needs.
