Problem with node state

[mafemuea]

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:

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

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

Thanks a lot.
