    hibernate tries to persist a second time

    Bob Morane Newbie

      hi,
      i am not sure if this is a seam or/and hibernate problem, so i try to ask here =)
      following scenario:
      i have a message that consists of child nodes, files in this case. the user opens a site where he can change the properties of an existing message and add/delete filenodes (using seam fileuploader), this site is backed by a SFSB.
      so the user adds two new files to the message, nothing is saved until he presses the submit button. then a method checks for the changes made and syncs them with the db, the code for the filenodes is:

      for (FileNode file : fileListadded) {
       if (!message.getChildren().contains(file)) {
       file.setParentNode(message);
       message.getChildren().add(file);
       file.setContentOwner(message.getContentOwner()); // messagebox
       entitymanager.persist(file);
       entitymanager.flush();
       }
      }
      [...]
      // update the message via merge
      

      everything works fine, the changes are synced, the new filenodes are persisted to the db. after that i raise an event so that another controller, which manages different messageboxes, knows that a message has changed.
      saveChangesOnExistingItem(message);
      // SeamEvent is my private container for custom events
      Events.instance().raiseEvent(SeamEvents.EVENT_VIEWMODEL_MESSAGE_CHANGED);
      return JSFOutcomes.OUTCOME_EDIT_COMPLETED;
      

      so the changes are saved, the event raised (the messageboxcontroller updates which messagebox to display) and the outcome redirects to the messagebox display, it shows the box which is the parent of the edited message.
      the problem is that hibernate tries to persist the new filenodes again after the outcome is returned. so the exceptions is thrown before the page is displayed.
