[jboss-user] [JBoss Seam] - Persist problem with Seam 1.1.0 and selectitems-1.1.1beta4

hi! I have a simple registration page where users can register. When they register they can select user roles. USer and role has relationship many-to-many. I use selectitems-1.1.1beta4 to display a selectionbox where the user can select 0-n roles. I also use a Seam-managed persistence context since it is required by selectitems. My action looks like this: @In(create=true) private EntityManager entityManager; @In(required = false) @Valid private User user; When I try to call entityManager.persist(user) I get the following strange error: at java.lang.Thread.run(Thread.java:595) Caused by: org.jboss.tm.JBossRollbackException: Unable to commit, tx=Transaction Impl:XidImpl[FormatId=257, GlobalId=lia/192, BranchQual=, localId=192] status=ST ATUS_NO_TRANSACTION; - nested throwable: (javax.persistence.PersistenceException : org.hibernate.AssertionFailure: null id in se.camitz.par.User ent ry (don't flush the Session after an exception occurs)) I says my Id is null. My user class has an autogenereated id so it should work: @Id @GeneratedValue(strategy=GenerationType.AUTO) @Column(name="Id") public Integer getId() { return id; } The interesting thing is that if I create a new User object in my action and copy all values to the new object and call entityManager.persist(newUser) then it works fine! User newUser = new User(); newUser.setName(user.getName()); newUser.setRoles(user.getRoles()); .... entityManager.persist(newUser) Any ideas someone???
