Every user tasks need to be rollback

uping

I am a beginner of Activiti.
I have a complicated process with more than 10 user tasks. As request from customer, every user tasks maybe failed and need to be rollback/rejected to last state. How do I handle this case? It's too complicated if I add a gateway for every user task, and it makes my BPMN diagram mess. Is there any simple way for this requirement?

What does that mean, exactly? What means the userTask fails?

If you have some custom escalation logic you want to apply to every userTask (i.e. a timer boundary event http://activiti.org/userguide/index.html#bpmnTimerBoundaryEvent), you could model it in a subprocess. You can then pass the parameters like "assignee" and escalation timers to the subprocess.

That means in every user task form, we need provide "Reject" option so they can rollback. I have read the link you provide, it doesn't solve my problem but thanks.

Hi,

What you could do is use an exclusive gateway and based on the outcome of the user task you can go back to a previous element.
That's not really a rollback, but you can still go back in the process definition.

My solution to this problem is :
you save the the actions into a database as a record.
When you need to revert the workflow to a specific stage, just restart the workflow and use the action records to do the tasks until the workflow goes to the point which you want to revert to.
