[jboss-user] [JBoss Seam] - Re: Seam form submission errors

[jbrosan]

It seems that I have all of the data from the form and that its crashing on the em.persist(user) line. I'm not sure why though.

UserModifyActionImpl.java

  | 
  | @Stateless
  | @Name("usermodifyaction")
  | public class UserModifyActionImpl implements UserModifyAction {
  | 
  | 	@In(create=true)
  | 	private UserImpl user;
  | 	
  | 	@PersistenceContext
  | 	private EntityManager em;
  | 	
  | 	
  | 	public String addUser()
  | 	{
  | 	      List existing = em.createQuery("select userName from UserImpl u where userName=:userName").setParameter("userName", user.getUserName()).getResultList();
  | 	      
  | 	      if (existing.size()==0)
  | 	      {
  | 	
  | 	        em.persist(this.user);
  | 	        //log.info("Registered new user #{user.username}");                               
  | 	         return "/admin/user/userlist.xhtml";                                                       
  | 	      }
  |         else
  | 	      {
  | 	         FacesMessages.instance().add("User #{user.userName} already exists");          
  | 	         return null;
  | 	      }

Any suggestions on what is could be causing this and/or suggested fix would be most welcome.
