I have an entity bean on these lines.. @Entity User { @Version int version; @Id String id; ... ... } Then I have a SLSB with this method: updateUser (User u) { @PersistenceContext EntityManager em; List dbUsers = em.createQuery("select from User u where u.name = 'user1').getResultList(); User dbUser = dbUsers.get(0); dbUser.setName("user2"); } i would have expected the version count of the user to be incremented. this does not happen. Then i tried with the following em.lock(dbUser, LockModeType.READ); and also em.lock(dbUser,LockModeType.WRITE); before the setter method. still the version does not get updated. What am i doing wrong here.. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3962070#...
