Assigning Taks to the same user when sent back

[zahidmaqbool]

Hello Everyone,

I am in great confusion, if anyone can help i would be really thankful.

Currently in my application, users log into the application and assign tasks to themselves from a pooled task list.

Now, I have something in my application that say Task "A" is completed and goes to TASK "B", then at Task "B" the user rejects the application and it has to go back to Task "A", where this task should be assigned to the same user who had earlier processed it from Task "A" to "B".

Here, I what to do except how to automatically assign the task back to the user who processed in the earlier stage.

If anyone can provide any hints or examples of this, I would be really helpful.

Hi,

I think that swimlanes is something that you are looking for

A swimlane, as fas as I understand, will keep the same actor. If TASK B is for a different actor then a swimlane will not solve this. What we did was to extend the taskInstance with our own object that keeps the information on the former actors on the task (Tasks can also be reassigned so you need to keep as fas history as needed). Then we used a Task Assignement Handler that checks for a flag to restore the former actor.

Thanks for your response, to keep track of previous users i am storing it now a variable in business process. Then i assign the task through my class.

It works fine. I thought there is a way to track all the users, but couldnt find one so had to do something.

Between I have found that jbpm_taskInstances does maintain a list of users assigned to tasks. So i believe even if we know the taskID of previous stage we can get this information.

jpechane is correct in suggesting swimlanes. Task A and Task B need to have different swimlanes. If there is a transition back from B to A, the original actor (or group of actors) will be assigned to Task A again. So no need to store this somewhere.
