Withdraw a task

[mdond]

Is it possible to withdraw a task?

Example:

start->task1->task2->end

user1 completes task1.
Nobody has accepted task2 and user1 notices that he has forgotten to enter some information therefore user1 clicks some action on the process to withdraw the current task and complete his former task1 again.

cheers,
Maarten

You will have to add your own operation, which calls the Activiti API to do that.

Sorry for being so late in replying:

I didn't find a possibility in the Activiti API to do something like this, can you give me a hint, where to look?
Or do you mean to model it explicitily in the workflow for every task and trigger the transition of the workflow?

No, what I meant is that this is not possible out of the box with Activiti, you will need to write your own Java operation and wrap it around the Activiti service calls.
