Bpel callbacks(human task)

Question

Hi,
i have a human task assigned to sequential list of users(2 users).On outcome updated by 1st user,i need to manipulate the task before it is routed to 2nd user.I thought the bpel callbacks would be helpful...but i could not..
By default,the onAssigned callback is called when 1st user updates the outcome and routed to 2nd user..But it is late when we want to manipulate the task in onAssigned callback,bcoz it is already been assigned...
OnTaskUpdated or OnTaskCompleted is not invoked..
...can anybody give some idea???
