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.
