Yes I did like that Please find the attachment of screenshots. For sake of avoiding name collision I renamed to in_owner but still the rule is not triggered. Also I noticed that the POEPLEASSIGNMENT_POTOWNERS is having only one entry(i.e, only 1 entry for GroupID)  though I have mapped both GroupID(mapped from process variable) and ActorID(mapped from task variable) this clearly tells that there is some thing wrong with task input variable in_owner. What Iam doing wrong here ? Somewhere I read that in order to refer task variable we need to use ${var_name} I did that aswell but no change in behaviour.

  when

    $task : Task()

    $params : HashMap(this["in_owner"] !=null)

then

    ....

  And Regarding group tasks : I need to get all Tasks no matter in which state they are(specifically Ready,Reserved,InProgress) for the specified group. And also no matter to which user the task is assigned. Iam only interested in a particular group task without any relation to a particular user. How can I get them ?

Hi Maciej,

  Input variable(in_owner) is mapped correctly as you can see from the attached debug window(Capture3.PNG) @ AbstractHTWorkItemHandler.createTaskContentBasedOnWorkItemParams

  I guess there is some issue with serialization of HashMap of parameters, I have added toString method in org.jbpm.services.task.impl.model.ContentDataImpl and added the following piece of code in TaskRuleServiceImpl.executeRules and it gives junk characters string in my case but where as if I run the test case LifeCycleLocalWithRuleServiceTest it gives proper SOP as "***************** Recieved params :{manager=John}". Is there any thing I need to do ?

            if (params != null) {

                System.out.println("***************** Recieved params :"+params);

                session.insert(params);

            }

Hi Maciej. Can you please help me what is wrong with this ? Do I need to do something with marshalling strategy ?

Awesome it works as below couple of points just for clarification

  1) Is it going to be a very costly operation since for every task created a rule will be fired and also a session will be created for execution of the rule ?

  2) I saw you are using AssignmentService and TaskServiceRequest in the test case. I can't import AssignmentService not sure what is the reason as it was giving some rule compilation error. And regarding TaskServiceRequest : How is this different than directly changing Task object like how you did for "Assign to mary"

    It is such an important feature and so It would be great if it could be documented with details about the usage.

3) Lastly can you please help me about retrieving group tasks specific to a group as discussed above in this thread ?
