jBPM6 - HumanTask's status doesn't change after being started nor completed

[jizuzqui]

Hi,

I'm trying to execute a simple workflow as a Java Application with jBPM 6.2.0-Final. The workflow is as it follows:

The first HumanTask is assigned to an actor called "tecnico1". After "tecnico1" completes his task, the second task is assigned to a second actor, "aprobador". Here is the java code for this workflow:

  // Task 1: Product Definition

  List<TaskSummary> listaActor1 = taskService.getTasksAssignedAsPotentialOwner(actor1, "");

  System.out.println(actor1 + " has " + listaActor1.size() + " assigned tasks");

  TaskSummary task = listaActor1.get(listaActor1.size() - 1);

  System.out.println(actor1 + " claims the task " + task.getName() + ". The task status is " + task.getStatus().name());

  taskService.claim(task.getId(), actor1);

  System.out.println(actor1 + " has received the task " + task.getName() + ". The task status is " + task.getStatus().name());

  taskService.start(task.getId(), actor1);

  System.out.println(actor1 + " has started the task " + task.getName() + ". The task status is " + task.getStatus().name());

  taskService.complete(task.getId(), actor1, null);

  System.out.println(actor1 + " has completed the task " + task.getName()

  + ". The task status is " + task.getStatus().name() + ". The task owner is "

  + task.getActualOwnerId());

  // Task 2: Product Approval

  List<TaskSummary> listaActor2 = taskService.getTasksAssignedAsPotentialOwner(actor2, "");

  System.out.println(actor2 + " has " + listaActor2.size() + " assigned tasks");

  task = listaActor2.get(listaActor2.size() - 1);

  System.out.println(actor2 + " has received the task " + task.getName() + ". The task status is " + task.getStatus().name());

  taskService.start(task.getId(), actor2);

  System.out.println(actor2 + " has started the task " + task.getName() + ". The task status is " + task.getStatus().name());

  taskService.complete(task.getId(), actor2, null);

  System.out.println(actor2 + " has completed the task " + task.getName()

  + ". The task status is " + task.getStatus().name() + ". The task owner is "

  + task.getActualOwnerId());

  ksession.fireAllRules();

Here is the output log:

tecnico1 has 1 assigned tasks

tecnico1 claims the task Definicion producto. The task status is Ready

tecnico1 has received the task Definicion producto. The task status is Ready

tecnico1 has started the task Definicion producto. The task status is Ready

tecnico1 has completed the task Definicion producto. The task status is Ready. The task owner is null

aprobador has 1 assigned tasks

aprobador has received the task Aprobacion Producto. The task status is Reserved

aprobador has started the task Aprobacion Producto. The task status is Reserved

aprobador has completed the task Aprobacion Producto. The task status is Reserved. The task owner is aprobador

¿Is it correct? I thought that task status should change...

Source project is attached.

Thank you!

Hi,

probably you must reload the task after every action. Give it a try.

You are right, status should change

+1 to jimmy001,

You need to refresh the task, because the status is changed but in the server, also.. are you using the RuntimeManager? I strongly recommend you using it so the task service gets configured accordingly.

Hi,

what do you mean with "refresh the task"?  How can I do that? I think I'm using RuntimeManager, but I'm not sure if I'm using it correctly. This is the code executed before retrieving and starting the tasks:

  KieServices ks = KieServices.Factory.get();

  KieContainer kContainer = ks.getKieClasspathContainer();

  KieBase kbase = kContainer.getKieBase("TallerProductosKB");

  Server server = Server.createTcpServer(new String[0]);

  server.start();

   Properties properties = new Properties();

   properties.load(ProcessMain.class.getResourceAsStream("/jBPM.properties"));

    // Configuring datasource

    PoolingDataSource pds = new PoolingDataSource();

    pds.setUniqueName(properties.getProperty("persistence.datasource.name", "jdbc/jbpm-ds"));

    pds.setClassName("bitronix.tm.resource.jdbc.lrc.LrcXADataSource");

    pds.setMaxPoolSize(5);

    pds.setAllowLocalTransactions(true);

    pds.getDriverProperties().put("user", properties.getProperty("persistence.datasource.user", "sa"));

    pds.getDriverProperties().put("password", properties.getProperty("persistence.datasource.password", ""));

    pds.getDriverProperties().put("url", properties.getProperty("persistence.datasource.url", "jdbc:h2:tcp://localhost/~/jbpm-db;MVCC=TRUE"));

    pds.getDriverProperties().put("driverClassName", properties.getProperty("persistence.datasource.driverClassName", "org.h2.Driver"));

    pds.init();

  // Creating RuntimeManager

  // Actors definition

  properties = new Properties();

  properties.setProperty(actor1_1, "admins,managers,users,PM");

  properties.setProperty(actor1_2, "admins,managers,users,PM");

  properties.setProperty(actor2, "admins,managers,users,PM");

  UserGroupCallback userGroupCallback = new JBossUserGroupCallbackImpl(properties);

  EntityManagerFactory emf = Persistence.createEntityManagerFactory("org.jbpm.persistence.jpa");

  RuntimeEnvironmentBuilder builder =

RuntimeEnvironmentBuilder.Factory.get().newDefaultBuilder().entityManagerFactory(emf).userGroupCallback(userGroupCallback) .knowledgeBase(kbase);

  RuntimeManager manager = RuntimeManagerFactory.Factory.get().newSingletonRuntimeManager(builder.get(), "");

  RuntimeEngine engine = manager.getRuntimeEngine(null);

  KieSession ksession = engine.getKieSession();

  TaskService taskService = engine.getTaskService();

  ProcessInstance instancia = ksession.startProcess("TallerProductos");

  System.out.println("Instancia creada: " + instancia.getId());

  ksession.fireAllRules();

Call this method again after calling the claim method:

listaActor1 = taskService.getTasksAssignedAsPotentialOwner(actor1, "");

And you should be able to see that the task was updated.

Yeah, that's was I did. Thank you all!
