Sendback to already completed Task of processInstance in Activiti

Question

How can I send back to a task which is marked as complete in a process instance.I am trying to use activiti engine APIs to achieve that but could not find any directly.

I was expecting something like

processEngine.getTaskService().sendBack(task.getId());

Any help on this is appreciated.

Answer 1

By adding sequence flow to every other step with an exclusive gateway and a conditional expression sendback is achievable.
