Hi,
When using Jbpm 3.2.3, I created a timer programmatically, which has always been working. This is my code to create a timer on the fly:
public static void createTaskReminder(JbpmContext jbpmContext, TaskInstance taskInstance, Date dueDate, String repeat, String timerName) {
| try {
| // getting data from the context
| Token token = taskInstance.getToken();
|
| // creating the action
| Delegation timedDelegation = new Delegation("workflow.jbpm.TaskReminder");
| Action timedAction = new Action(timedDelegation);
|
| // creating the timer
| Timer timer = new Timer(token);
| timer.setName(timerName);
| timer.setAction(timedAction);
| timer.setRepeat(repeat);
| timer.setDueDate(dueDate);
| timer.setGraphElement(taskInstance.getTask().getTaskNode());
| timer.setTaskInstance(taskInstance);
|
| // scheduling the timer
| SchedulerService schedulerService = (SchedulerService) jbpmContext.getServices().getService(Services.SERVICENAME_SCHEDULER);
| schedulerService.createTimer(timer);
|
| }
| catch (Exception e) {
| e.printStackTrace();
| }
| }
I am now using the latest 3.2.6 SNAPSHOT, but when closing the jbpmContext, I get the following exception:

Any ideas what has changed, or what I am doing wrong?
