First, I apologize because my English language writing is not good enough.
My question is how can I find the previous task assignee . According to this website content, i understood that one of the solutions of this problem is to store previous task assignee in process instance variable. but when exist fork and join in process, this solution does not work.for example suppose that when task1 completed parallel task2 and task3 created. then when task2 completed before task3, assignee of task2 stored in process variable and then when in task3 i want go to previous task assignee, result is task2 assignee . but correct result should be Task1 assignee.
