    FlushMode of EntityManager

    Tina Ng Newbie
      I have an abstract action who defines the conversation (start and end)

      @AutoCreate
      @Scope(ScopeType.CONVERSATION)
      public abstract class MainAction {
          @In
          private EntityManager entityManager;

          @Create
          public void initComponent() {
              createConversation();
              logger.info("createAction");
              init();
          }

          private void createConversation() {
              Conversation.instance().begin();
              Conversation.instance().changeFlushMode(FlushModeType.MANUAL);
          }

          public void save() {
              logger.info("Commiting transaction");
              entityManager.flush();
              logger.info("Transaction commited");
              FacesMessages.instance().addFromResourceBundle(Severity.INFO,
                      "general.saveMessage");
              endConversation();
              createConversation();
          }

          private void endConversation() {
              Conversation.instance().end(false);
          }

          public abstract void init();

          /**
           * Getteur de l'attribut entityManager.
           *
           * @return EntityManager la valeur de entityManager
           */
          public EntityManager getEntityManager() {
              return entityManager;
          }
      }

      All the actions for each screen extends from MainAction.
      Eventhough in MainAction I start CONVERSATION with FlushMode type MANUAL, in each action (extends MainAction) I receive Flush type is null (Note that in GestionPrestActAction who extends MainAction, I retrieve EntityManager by using getEntityManager in MainAction). I don't understand why. And that's also the reason why when I modify something, the modification is committed directly to DB without waiting for entityManager.flush()

      Here is the code of an action extends MainAction

      @AutoCreate
      @Scope(ScopeType.CONVERSATION)
      @Name("gestionPrestAct")
      public class GestionPrestActAction extends MainAction {
          @Logger
          private Log               logger;

          @Override
          public void init() {
              activiteToModif = new Activite();
              allActivites = activiteService.getAllActivites();
              initDataModel();
          }

          @SuppressWarnings("unchecked")
          @Factory(autoCreate = true, value = "prestationsAll")
          public void initDataModel() {
              logger.info("initDataModel");
              prestationsAll = prestationService.getAllPrestations();
              Collections.sort(prestationsAll, new Prestation.PrestationComparator());
              logger.info("Flush mode type " + getEntityManager().getFlushMode());
          }
      }

      Is there someone who could tell me the reason?
      Thanks
      Tina
