The context should not be shared!!! Open it and close it per webrequest as you mention further on. What do you mean by different PO's for different clients? Do they all work on the same processinstance at the same time? Or do you have multiple tasks parallel tasks for different actors? In that case the taskvariables are created at the moment the task is created with the values of processvariables of that moment. Changes in those are not reflected in the already created tasks.
