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

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:

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:

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();

Any ideas someone???
