[jboss-user] [JBoss Seam] - Re: duplicate id error using ICE data paginator - need help

I am really stuck on this issue - maybe I am doing something wrong in the bean?

Greatful for any feedback:

  | 		
  | 		log.debug("Got a List back  empty=#0", Boolean.valueOf(m_availableSpaces.isEmpty()));
  | 	}
  | 
  | 	public String addSpace()
  | 	{
  | 		// create the full "public.xxx" name and check that it is a
  | 		// valid space name
  | 		//
  | 		String tmpSpace = "public."+m_spaceInput;
  | 		if(!SpaceNameValidator.isSpaceNameValid(tmpSpace))
  | 		{
  | 			FacesMessages.instance().add("spaceInput", "Invalid space name");
  | 			return "error-space-add-invalid-name";
  | 		}
  | 		// Check if space exists

  | 		em.persist(p);
  | 		em.persist(sa);
  | 		log.info("Added space #0 for user #1", p.getSpaceName(), m_currentUser.getLogin());
  | 		getAvailableSpaces();
  | 		// Clear this value for new input
  | 		m_spaceInput = "";

  | 	}
  |

  | 	{
  | 		m_spaceInput = space;
  | 	}
  |
