Release task in LocalTaskService in jBPM5.2

[rahulamt]

Hi all,

This is my use case: A task is pending with a Role. Some user with that role claims the task. Now the user do not want to work on that task. He want to release that task to role pool.

The above action can be achieved through org.jbpm.task.TaskService.release(taskId, idRef). But unfortunately this API is not working.

So I dug dip into the code details ,I could find the following in the LocalTaskService

public void release(long taskId, String userId) {

        taskServiceSession.taskOperation(Operation.Release, taskId, userId, null, null, null);

    }

and in the TaskServiceSession for this taskOperation

               switch (operation) {

                case Claim: {

                    taskClaimOperation(task);

                    break;

                }

                case Complete: {

                    taskCompleteOperation(task, data);

                    break;

                }

                case Fail: {

                    taskFailOperation(task, data);

                    break;

                }

                case Skip: {

                    taskSkipOperation(task, userId);

                    break;

                }

                case Remove: {

                          taskRemoveOperation(task, user);

                          break;

                }

                case Register: {

                          taskRegisterOperation(task, user);

                          break;

                }

            }

there is no switch case for release operation. The same for the postTaskOperations.

Can anyone explain? Am I not supposed to use release for the use case above described?

Please help!!!

The cause is that the Task instance is not persisted in the database so the status is not updated.

I am adding a case statement here after skip.

case Skip: {

                      postTaskSkipOperation(task, userId);

                      break;

                  }

case Release: {

                            postTaskReleaseOperation(task);

                            break;

                  }

and in postTaskReleaseOperation(task); added the following...

private void postTaskReleaseOperation(Task task) {

                    // We may add some even support trigger here.

              persistInTransaction(task);    

          }

I am using postgres database.

I am facing the same issue with the claimed task.

Should I raise the jira issue for this?
