Dear all,
I have the following mapping :



I don't know if unsaved-value and sequence are compliant. Actually, even if the key is different from 0, Hibernate creates a new sequence number when saving my object.
Therefore, is it possible to have a sequence and setting unsaved-value or does hibernate trigger each time the sequence ?
Thanks

unsaved-value is just used for cascades and saveOrUpdate, if you use session.save() Hibernate will of course allways save your object and therefore generate an id for it.
