jBPM process not completed (sometimes)

[lauradp]

Hello everybody,

I'm facing a strange problem on my bjpm process.

My process contains a human task (managed by an AsynchHornetQHTWorkItemHandlet), executed (started and then completed) by an extenal application through human task API (taskClient.start(...) taskClient.complete()). Sometimes (25-30% af times) after the human task has been completed the process doesn't continue its execution. When the process blocks human task's record in workItemInfo table is not deleted from the database..

Can anyone suggest me a solution  to this problem?

The workItemHandler uses the session you inject into its constructor to continue the process:

https://github.com/droolsjbpm/jbpm/blob/5.4.x/jbpm-human-task/jbpm-human-task-core/src/main/java/org/jbpm/process/workitem/wsht/AsyncGenericHTWorkItemHandler.java#L270

is the session available and not disposed at the time you do task.complete?

Thanks for your answer!

I create a session, with the same sessionId

private StatefulKnowledgeSession createKSession(int sessionId, String processPath) {

                    // Create the kbuilder

                    KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();

                    // Add simpleProcess.bpmn to kbuilder

                    kbuilder.add(ResourceFactory.newFileResource(processPath), ResourceType.BPMN2);

                    System.out.println("Compiling resources");

                    // Check for errors

                    if (kbuilder.hasErrors()) {

                              if (kbuilder.getErrors().size() > 0) {

                                        for (KnowledgeBuilderError error : kbuilder.getErrors()) {

                                                  System.out.println("Error building kbase: " + error.getMessage());

                                        }

                              }

                              throw new RuntimeException("Error building kbase!");

                    }

                    // Create a knowledge base and add the generated package

                    KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase();

                    kbase.addKnowledgePackages(kbuilder.getKnowledgePackages());

                    // return a new statefull session

                    return kbase.newStatefulKnowledgeSession();

          }

and then I use this session to complete my workItem.

I never dispose my session.

May my problem be due to this issue: https://issues.jboss.org/browse/JBPM-3582?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel??

It could happen because the task complete listener are not registered for some reason:

https://github.com/droolsjbpm/jbpm/blob/5.4.x/jbpm-human-task/jbpm-human-task-core/src/main/java/org/jbpm/process/workitem/wsht/AsyncGenericHTWorkItemHandler.java#L120

Maybe you can debug to see if TaskCompletedHandler(https://github.com/droolsjbpm/jbpm/blob/5.4.x/jbpm-human-task/jbpm-human-task-core/src/main/java/org/jbpm/process/workitem/wsht/AsyncGenericHTWorkItemHandler.java#L216) is being called..
