Hi All,
Please help me, I am newbie at JBPM 4.x. I have a problem with leaving a state programmatically in timer listener. I always get exception like this:
12 Apr 2010 11:21:11 ERROR org.jbpm.pvm.internal.cmd.ExecuteJobCmd - exception while executing 'timer[30|2010-04-12 11:21:11,412|timeout]'
org.jbpm.api.JbpmException: execution[ADSLProvisioning.22] is not active: inactive-scope
at org.jbpm.pvm.internal.model.ExecutionImpl.checkActive(ExecutionImpl.java:1024)
at org.jbpm.pvm.internal.model.ExecutionImpl.take(ExecutionImpl.java:466)
at org.jbpm.pvm.internal.model.ExecutionImpl.takeDefaultTransition(ExecutionImpl.java:449)
at uk.co.upshot.jbpm.handler.OrderStatusChecker.notify(OrderStatusChecker.java:62)
at org.jbpm.pvm.internal.wire.usercode.UserCodeEventListener.notify(UserCodeEventListener.java:39)
What I would like to do is checking status from database repeatedly every X minutes. When it found certain status e.g. COMPLETED it should go to the next state, otherwise it will repeat until that status is reached.
Currently I implement it as a state with a repeated timer:
<state name="Check Order Status">
<on event="timeout">
<timer duedate="10 minutes" repeat="10 minutes"></timer>
<event-listener expr="#{OrderStatusChecker}"></event-listener>
</on>
<transition name="to-status-decision" to="status-decision"></transition>
</state>
and on the timer listener:
public class OrderStatusChecker implements EventListener {
public void notify(EventListenerExecution event) throws Exception {
// Check status.
String status = ...... get status from Database ...
event.getProcessInstance().setVariable("status", status);
if (status.equals("COMPLETED")) {
// Leave current state
ActivityExecution execution = (ActivityExecution) event.getParent();
execution.takeDefaultTransition();
}
}
}
Is it possible to do that in JBPM? If it's not possible, is there any workaround for my case?
I use JBPM4.3 with spring 2.5.
Thank you.

Nugroho
