[jboss-user] [JBoss Seam] - Event not raised with annotations - Bug?

[ruettimac]

Hi,

I have two methods raising an event - one raises the event, the other not. If I raise the event programmatically it works, but not while I am annotating the raise of the event.

First the method which does not raise the event with annotations:


  | @RaiseEvent(value=SeamConstants.EVENT_SPORTEQUIPMENT_CHANGED)
  |     public String deleteSportEquipment(final SportEquipment pSportEquipment) throws PersistencyException {
  |         Validate.notNull(pSportEquipment, "Argument pSportEquipment is mandatory");
  | 
  |         try {
  |             SportEquipment toDelete = mEntityManager.merge(pSportEquipment);
  |             pSportEquipment.getCustomer().getSportEquipments().remove(pSportEquipment);
  |             mEntityManager.remove(toDelete);
  |         } catch (final Exception pException) {
  |             mLog.error("Failed to delete sport equipment #0 of customer #1", pException, pSportEquipment.getName(), pSportEquipment.getCustomer().
  |                     getLogin().
  |                     getSynonym());
  |             throw new PersistencyBackendException("exception.persistencybackend", pException);
  |         } finally {
  |             //Events.instance().raiseEvent(SeamConstants.EVENT_SPORTEQUIPMENT_CHANGED);
  |         }
  | 
  |         return NavigationConstants.REDISPLAY;
  |     }
  | 

The constant NavigationConstants.REDISPLAY simply returns null.

The second method which raises the event with annotations:

@RaiseEvent(value=SeamConstants.EVENT_SPORTEQUIPMENT_CHANGED)
  |     public String persistSportEquipment(final SportEquipment pSportEquipment) throws PersistencyException {
  |         Validate.notNull(pSportEquipment, "Argument pSportEquipment is mandatory");
  | 
  |         SportEquipment sportEquipment = null;
  | 
  |         // update first if id already set, if id is null we have a fresh sport equipment
  |         if (null != pSportEquipment.getId()) {
  |             sportEquipment = mEntityManager.merge(pSportEquipment);
  |         } else {
  |             sportEquipment = pSportEquipment;
  |             sportEquipment.getCustomer().getSportEquipments().add(sportEquipment);
  |         }
  | 
  |         try {
  |             mEntityManager.persist(sportEquipment);
  |         } catch (final Exception pException) {
  |             mLog.error("Failed to save changed for sport equipment #0 of customer #1", pException, pSportEquipment.getName(), pSportEquipment.getCustomer().
  |                     getLogin().
  |                     getSynonym());
  |             throw new PersistencyBackendException("exception.persistencybackend", pException);
  |         } finally {
  |             //Events.instance().raiseEvent(SeamConstants.EVENT_SPORTEQUIPMENT_CHANGED);
  |         }
  | 
  |         return NavigationConstants.SUCCESS;
  |     }

While looking at the code; Do you see anything that is wrong? The only difference I see is the return value. I validated, that if null is returned, the event is not fired. But If I return a value, the event is fired.

I suppose this is a bug?!
