Thanks for your reply. May be what I say isn't enough clear,Sorry for my poor english! task transfer == bulk reassign == loop over all tasks and reassign. I quite agree with this point ? for consign,I think consign!=assign to someone else,JBPM has an assign method in the api,but it change the original actor to new actor,I don't want to change the original task actor?For example, at a actor be on business trip, temporarily entrust his task to other person.
