JBPM Consecutive process instances do not reach human task

[suchinder.singh]

Hi Guys,

I am facing an issue where consecutive process instances do not reach human task. I have a workflow with two human tasks connected to each other (picture attached). I start two process instances consecutively. Both the process instances reach the first human task and I can see them in the tasks assigned to the actor of the first human task. Then I proceed them to the second human task. But only the first process instance reaches the second human task, and I see only one task assigned to the actor of the second human task. I am attaching my source code as well.

Many Thanks

Code to view tasks assigned to actor

TaskClient client = new TaskClient(new MinaTaskClientConnector("client 1",
                    new MinaTaskClientHandler(SystemEventListenerFactory.getSystemEventListener())));
client.connect("127.0.0.1", 9123);

BlockingTaskSummaryResponseHandler taskSummaryResponseHandler = new BlockingTaskSummaryResponseHandler();
client.getTasksAssignedAsPotentialOwner(actor, "en-UK", taskSummaryResponseHandler);
taskSummaryResponseHandler.waitTillDone(MAX_WAIT_TIME);
List<TaskSummary> tasks = taskSummaryResponseHandler.getResults();

Code to proceed human task

TaskClient client = new TaskClient(new MinaTaskClientConnector("client 1",
                    new MinaTaskClientHandler(SystemEventListenerFactory.getSystemEventListener())));
client.connect("127.0.0.1", 9123);

BlockingTaskOperationResponseHandler responseHandler = new BlockingTaskOperationResponseHandler();
client.start( taskid, userid, responseHandler );
responseHandler.waitTillDone(MAX_WAIT_TIME);

responseHandler = new BlockingTaskOperationResponseHandler();
client.complete( taskid, userid, null, responseHandler );
responseHandler.waitTillDone(MAX_WAIT_TIME);

Code to start process

KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();
kbuilder.add(ResourceFactory.newInputStreamResource(bpmnStream), ResourceType.BPMN2);
KnowledgeBase kbase = kbuilder.newKnowledgeBase();

StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession();
MinaHTWorkItemHandler humanTaskHandler = new MinaHTWorkItemHandler(ksession);
ksession.getWorkItemManager().registerWorkItemHandler("Human Task", humanTaskHandler);

ProcessInstance process  = ksession.startProcess(processname, null);
