Hello Ricardo,
Thanks for the reply. However using a stateless session doesnt help my
case. What I want, is an alternative means to changing the foreign key
value. At the moment, the closes I have come to fully mapping the foreign
key is:
Map(x => x.ParentID).ReadOnly();
which allows me to read the ID of the parent but of course I can't change
it.
