I think I'm closer, but still not quite able to get this to work.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>I've tried canceling the old timer (canceling portion works great), but setting up the new timer seems to give issues. </p><p><br/>The route I'm trying is:</p><p>((TimerNodeInstance) nodeInstance).cancel();</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>// create timerInstance</p><p>TimerInstance timerInstance = new TimerInstance();</p><p>timerInstance.setDelay(TimeUtils.parseTimeString("5s")); // hard-code to X seconds</p><p>timerInstance.setPeriod(0); // hard-code to a period of 0</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>then I register the new timerInstance with the processInstance:</p><p>((InternalProcessRuntime)((WorkflowProcessInstance) nodeInstanceContainer).getKnowledgeRuntime().getProcessRuntime()).getTimerManager().registerTimer(timerInstance, (org.jbpm.process.instance.ProcessInstance) nodeInstanceContainer);</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Lastly I set the timerInstanceId into the TimerNodeInstance:</p><p>((TimerNodeInstance) nodeInstance).internalSetTimerId(timerInstance.getId());</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>My trouble is the new timer event never fires.  The old one is definitely canceled, if I set it for a short value (like 5 seconds) it doesn't fire after cancellation.  But it's like the new timer is missing something, as it never fires either no matter what delay value is set.  </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>I've also tried modifying the IntervalTrigger time of the original timer, but this change doesn't seem to get picked up either.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Both of these I've done while the processInstance.disconnect() was called, and processInstance.reconnect() is called afterwards.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Thanks for any help/suggestions!</p></div>
