Could you teach me how can I delegate the task to other user?

[alvin_ge]

I want to do a feature in my workflow: When user can not complete his task, the user wants to delegate this task to another user.

Who can tell me how can I to do? Where is it on 'User Guide'?

Sorry about my English.

taskService.setAssignee(newAssignee) or delegate()
