NOTE: As of Hibernate 3.0.1, transactional Hibernate access code can also be coded in plain Hibernate style. Hence, for newly started projects, consider adopting the standard Hibernate3 style of coding data access objects instead, based on SessionFactory.getCurrentSession(). This is actually not really a Seam question, it's a question about optimistic concurrency in Hibernate. In some sense, once you've gotten a StaleObjectStateException, it's too late. You have to throw out your whole Hibernate session, which is tough to do in general.

In your example, unsaved-value="null" seems pretty pointless, since I suspect the "sensible default" for a Long is null. It's more useful for primitive types (e.g. int ), which cannot be null , and the default unsaved-value of 0 may be undesirable in some applications ( 0 being a perfectly valid number value). Hibernate 5 - merge() Example - In this article, we will show you how to use Session.merge() method to merge an entity in the Hibernate Application. Hibernate 5 - Delete or Remove an Entity Example - In Hibernate, an entity can be removed from a database by calling the Session.delete() or Session.remove(). Using these methods, we can remove a transient or persistent object from datastore.
