[jboss-user] [JBoss Seam] - Re: best way of using application scope constants?

[jazir1979]

I'm doing a similar thing to this using a SLSB with application scoped @Factory methods.  It works well.


  | @Stateless
  | @Name("factory")
  | public class FactoryActionBean extends BaseActionBean implements FactoryAction {
  |     @In(create = true, value = "entityManager")
  |     protected EntityManager em;
  | 
  |     /** {@inheritDoc} */
  |     @Factory(value = "statusList", scope = ScopeType.APPLICATION)
  |     public List<Status> getStatuses() {
  |         return  service.findReservationStatuses(em);
  |     }
  | 

Watch out though, using the above list with <s:convertEntity/> broke in Seam 2 Beta 1 due to JBSEAM-1487, but this is now fixed in CVS, thanks to Pete.
