> Hibernate has two ways of specifying a value for primary key:
> 1. Assign a value before handing it over to Hibernate
> 2. Have Hibernate generate the value before persisting
> In my project I have objects of both of the above specified types. In other words I assign value for the primary key for some the objects (lets call these objects "assigned") and for others I have Hibernate generate the value before persisting (lets call these objects "generated"). Since Hibernate annotations does not support "unsaved-value", I do not have a way of specifying "unsaved-value" strategy. While my "generated" objects work perfectly with Hibernate's default "unsaved-value" strategy, I see wrong (but expected) behaviour when I try to persist an "assigned" object that is already present in the database in that, I get StaleStateException instead of DataIntegrityViolationException
