Dynamic human task assignment, jbpm 6.x

[kaveh khani]

Hi

I want to assign human task to users dynamically. I write this code in where I create the process instance:

Map<String, Object> params = new HashMap<String, Object>();

params.put("assignee", "Jasem");

ProcessInstance processInstance = ksession.startProcess("myBpmn", params);

And in bpmn definition, in the user task node:

                ActorId=#{assignee}

I logged the assignee variable in On Entry Actions of that node like this:

              System.out.println("------------   kcontext.getVariable(assignee)  :  " + kcontext.getVariable("assignee")  +"   ---------------");

And it prints :

              ------------   kcontext.getVariable(assignee)  :  Jasem   ---------------

"Jasem" is registered as a user in and I checked it out in table "OrganizationalEntity". So it looks like everything is ok. But when I want to list the tasks assigned to "Jasem" , it gives me back an empty list. 

For other tasks that assigned to user inside bpmn definition, something like : ActorId=SomeRegisteredUser, everything is alright and this task is shown in "SomeRegisteredUser" task list. Any idea?

Thanks for reading.

HI,

I tried with same scenario at my end,and its working fine for me. I have attached standalone java code and BPMN process for your reference.

Take a look at it.Can you share simple reproducer ?

Hi Abhijit and thank you for your response

Your code and process definition looks same as mine, but I could not figure out why it has different behavior. So, I guess in DB in Task.actualOwner_id and createdBy_id , TaskEvent.userId, AuditTaskImpl.actualOwner_id and createdBy_id , PeopleAssignments_PotOwners.entityId, you have correct values, right? In my DB, they are correct just for user tasks assigned statically in bpmn definition, something like :

                    ActorId=SomeRegisteredUser

I attach my process definition and java class. I will be thankful if you take look at it.

Thanks in advance.

Hi everybody.

I resolved my problem by comparing my process definition file with what Abhijit sent. So I write this, and I hope it can resolve others who encounter the same problem. In the process definition, I set the variable "assignee" like picture 1. Compare my new process definition file with older one to find the differences between them and what caused this problem. To find out what does "assignee" is, read my previous attached files and comments.

With special thanks of Abhijit, good luck.

Hi Kaveh,

Can you please specify version of Jbpm you using becausse I have tried with same but not getting tasks for passed user in #{assignee} process variable.

Your response will be helpful for me..

Thanks in advance.

Hi Amol

I used jbpm 6.2. If you are using any 6.x version, I guess the problem is not the version you are using. Read my code, and the code provided by Abhijit again. Maybe you set the the 'assignee' improperly. Do you assign it to 'ActorId' property?
