Hey guys,
I've got a process that I run the 1st half until it hits a timer, at which time I persist the process instances to the DB. This portion works fine.
When retrieving the sessions, I find (based on stack exceptions & debugging) JBPM calls JPAWorkItemManager.internalExecuteWorkItem before I can register my workItemHandlers.
Right now I'm calling JPAKnowledgeService.loadStatefulKnowledgeSession, and immediately after calling ksession.getWorkItemManager().registerWorkItemHandler, but it seems like some kind of race condition occurs and the engine wants to execute immediately upon loading from the database.
Has anyone else run into this problem before?

[jBPM] - Problem in a process with a event-based timer and JPAWorkingMemoryDbLogger

Hi Guys,
I have a very simple process with a timer event:
http://community.jboss.org/servlet/JiveServlet/showImage/2-621274-16871/p... http://community.jboss.org/servlet/JiveServlet/downloadImage/2-621274-168...
The timer has a timeCylce of 500ms. The scripts simply set a variable (message1 and message2) that i look to see of the scripts has been executed.
My test see that -after the prcess start- the first task is executed, waits for 1000ms and then check the that the second task has been executed (inspecting the message2 variable). Also the test check that the process is completed.
The Task2 script task containt that code:
<bpmn2:script>
System.out.println("Executing Script Task 1");
kcontext.setVariable("message","Executed Script Task 1");
</bpmn2:script>
That works perfectly...at least until I add:
JPAWorkingMemoryDbLogger logger = new JPAWorkingMemoryDbLogger(session);
When I do that, it seems that:
- The timer does not trigger the "Script Task 2" task.
- The error below appears in the console:
Hibernate: insert into NodeInstanceLog (id, log_date, nodeId, nodeInstanceId, nodeName, processId, processInstanceId, type) values (null, ?, ?, ?, ?, ?, ?, ?)

If we use cutom workitem handler as mentioned below and fireUntilhalt to invoke rules in reactive mode. While debugging, I found that before completing first task(line in blue & bold), it fires the rule which is active. After running of rule, it get back to end of completeworkitem.It creates a problem an thrpw an exception mentioned below.
WorkItemHandler
public class MyHumanChangingValuesSimulatorWorkItemHandler implements WorkItemHandler {
private static int counter = 1;
private WorkItemManager workItemManager;
private long workItemId;
private Map<String, Object> results;
private Emergency currentEmergency;
public void executeWorkItem(WorkItem workItem, WorkItemManager workItemManager) {
this.workItemId = workItem.getId();
this.workItemManager = workItemManager;
currentEmergency = (Emergency) workItem.getParameter("emergency");
currentEmergency.setRevision(currentEmergency.getRevision() + counter);
}
public void abortWorkItem(WorkItem workItem, WorkItemManager workItemManager) {
}
public void completeWorkItem() {
results = new HashMap<String, Object>();
results.put("emergency", currentEmergency);
workItemManager.completeWorkItem(workItemId, results);
}
}

Hi All,
I am facing one problem when completing a Human task. The problem arises when I use Spring drools integration. I am getting the ksession from spring bean. using that I am starting the process Instance. The process contains one human task. I am using SyncWSHumanTaskHandler and LocalTaskService. On call of task completion it throws exception as below
