Anyone figured this out ?

I have some simple examples using escalation and deadlines here:

https://github.com/esteban-aliverti/JBPM-Samples/tree/master/Simple-Task-Life-Cycle-Sample

They are very simple examples, but I think they will serve as a starting point for you.

Finally got it working..... a bit. However, I am not using any processes. Just creating task and setting all those deadline things. The emails are being sent out as notifications but I get a NullPointerException like this.

java.lang.NullPointerException

          at org.jbpm.process.workitem.email.EmailWorkItemHandler.executeWorkItem(EmailWorkItemHandler.java:94)

          at org.jbpm.task.service.DefaultEscalatedDeadlineHandler.executeEmailNotification(DefaultEscalatedDeadlineHandler.java:235)

          at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source)

I believe this is because I am not setting any WorkItemManager, which I dont have because I dont have any process.

Is my understanding correct.
