I'm using activiti 1.5.22.
I have created some processes, and each process can call to another as calledActiviti.
----- Process A (task A1, task A2)
----- Process B (task B1, task B2)
------ Process C (task C1, task C2).
Now, in task C1, I want show all process history from start to end by order ( A1, A2, B1, B2, C1)
How can I do it ?
