hi,

When I use JPAKnowledgeService and LocalTaskService, the process won't continue when complete the 2nd Human Task. 


the following is the code fragment




|  | Environment env = KnowledgeBaseFactory.newEnvironment(); |
|  | env.set( EnvironmentName.ENTITY_MANAGER_FACTORY, Persistence.createEntityManagerFactory("org.jbpm.persistence.jpa")); |
|  | env.set( EnvironmentName.TRANSACTION_MANAGER,TransactionManagerServices.getTransactionManager()); |
|  |  |  |  |
|  | Properties properties = new Properties(); |
|  | properties.put("drools.processInstanceManagerFactory", "org.jbpm.persistence.processinstance.JPAProcessInstanceManagerFactory"); |
|  | properties.put("drools.processSignalManagerFactory", "org.jbpm.persistence.processinstance.JPASignalManagerFactory"); |
|  | KnowledgeSessionConfiguration config = KnowledgeBaseFactory.newKnowledgeSessionConfiguration(properties); |
|  | KnowledgeBase kbase = readKnowledgeBase();  -- read knowledgebase |
|  |  |
|  | ksession = JPAKnowledgeService.newStatefulKnowledgeSession(kbase, null, env); |
|  |  |
|  | EntityManagerFactory emf = Persistence.createEntityManagerFactory("org.jbpm.task"); |
|  | org.jbpm.task.service.TaskService taskService = new org.jbpm.task.service.TaskService(emf, SystemEventListenerFactory.getSystemEventListener()); |
|  |  |
|  | LocalTaskService localTaskService = new LocalTaskService(taskService); |
|  | LocalHTWorkItemHandler localHTWorkItemHandler = new LocalHTWorkItemHandler(localTaskService,ksession, OnErrorAction.RETHROW); |
|  | localHTWorkItemHandler.setLocal(true); |
|  | localHTWorkItemHandler.connect(); |
|  | ksession.getWorkItemManager().registerWorkItemHandler("Human Task", localHTWorkItemHandler); |
