How to undo or redo human task in a process instance?

thomas.setiabudi Nov 22, 2012 12:42 AM

Hi,

in a process instance, is it possible to undo or redo human task without stopping the process instance?

Lets say if we have two sequential human task, human task A, then human task B.

After user completes human task A, and before human task B is complete, how do we provide a feature for user to undo or to redo human task A?

Regards,

Thomas Setiabudi

hi,

I don't think you can undo a completed task, basing on the task life cycle. http://docs.jboss.org/jbpm/v5.3/userguide/ch.human-tasks.html#d0e5129

But you can add an event or connection or any other method to re-enter this task node in the process. A new task instance will be created. You may need to manually 'rollback' what you have done to your business data before re-enter this task node.

Hi Ted Pan,

Thanks for your answer.
Guess you are right, we have to provide event or connection or any other method to re enter the task node and manually rollback our process.

there is a concern that by using process flow engine like jbpm our process become more rigid, but I guess we have to handle it.

here is a sample scenario, consider a self performance review system:
1. the employee need to make a self review and saves it on the system
2. the manager need to approve the review, If it is approved then the process ends, if it is rejected, then the employee needs to redo his task to edit / modify the self review.

An alternative to this would be to consider ad hoc process so it can be decided almost at any time what activity should be activated.

Hi Maciej,

Yes that solusion make sense too, maybe we should consider using ad hoc process in these kind of scenario.

Thank you
