    Problem with node state

    eva Fdez Newbie

      Hello everybody.

      When it finish a task of my workflow has to wait (10 days, it's customizable), to advance to the next task (of another node).
      I tested with a 'node state' between the two nodes happend the following error:

      Caused by: org.hibernate.TransientObjectException: object references an unsaved transient instance - save the transient instance before flushing: org.jbpm.graph.def.Action

      Thanks a lot.

          You did not mention it but I concluded you are using jBPM 3.x. So I can't help you since I use 4.x. But I advise you to post your process definition and a unit test. Also see the post about reporting problems.

            Hello

            I post more information about my problem:

            I use jBPM 3.2.6.

            This is a part of workflow:

            .....
             <task-node name="Recepcion de catalogos">
             <description>
             Recepción de catálogos
             </description>
             <task name="Recepcionar catalogos">
             <description>
             recepcionarCatalogos.do
             </description>
             <assignment class="*.*.*.bussiness.jbpm.handler.assignment.AsignaPoolActorTarea"></assignment>
             </task>
             <transition to="Esperar para desmontar"></transition>
             </task-node>
             <state name="Esperar para desmontar">
             <event type="node-enter">
             <action name="Esperar para desmontar" class="*.*.*.bussiness.jbpm.handler.action.ConfigurarPlanificadorDesmontaje"></action>
             </event>
             <transition to="Valor mayor 500 mil"></transition>
             </state>
             <decision name="Valor mayor 500 mil">
             <handler class="*.*.*.bussiness.jbpm.handler.decision.ValorMayor500milEuros"></handler>
             <transition to="Solicitud desmontaje" name="No"></transition>
             <transition to="Solicitud de escolta desmontaje" name="Si"></transition>
             </decision>
            .....
            


            The handler class "ConfigurarPlanificadorDesmontaje":

             public void execute(ExecutionContext executionContext) throws Exception {
             try{
             logger.debug("[execute] Inicio");
             BusinessCalendar businessCalendar = new BusinessCalendar();
             Token token = executionContext.getToken();
             logger.debug("[execute] token name: " + executionContext.getToken());
             Timer timer = new Timer (token);
             timer.setName("TimerDesmontaje");
            
             Delegation delegation = new Delegation("*.*.*.bussiness.jbpm.handler.action.SalirPlanificadorDesmontaje");
             executionContext.getJbpmContext().getSession().save(delegation);
            
             Action action = new Action ();
             action.setName("Salir de planificador");
             action.setActionDelegation(delegation);
             timer.setAction(action);
             timer.setGraphElement(executionContext.getNode());
            
             String tiempo = "2 business minutes"; //TODO: Value dinamic, go to BD
             Duration duration = new Duration(tiempo);
             Date dueDateDate = businessCalendar.add(new Date(), duration);
             timer.setDueDate(dueDateDate);
            
             SchedulerService schedulerService = (SchedulerService) Services.getCurrentService(Services.SERVICENAME_SCHEDULER);
             schedulerService.createTimer(timer);
             logger.debug("[execute] Fin");
             }catch(Exception e){
             throw e;
             }
             }
            
            


            And the handler class "SalirPlanificadorDesmontaje":
            public void execute(ExecutionContext context) throws Exception {
             try{
             logger.debug("[execute] Inicio");
            
             context.leaveNode();
             logger.debug("[execute] Fin");
             }catch (Exception e) {
             throw e;
             }
             }
            


            When it finish the task "Recepcion de catalogos", my workflow should wait time (String tiempo = "2 business minutes"; //TODO: Value dinamic, go to BD) before running the decision node "Valor mayor 500 mil", but happend the error:

            Any idea to solve my problem? There a way to model the workflow to do I need?

            Thanks a lot.
