Dear Vinod, BPMN 2.0 explicitly refers to WS-HumanTask as implementation of a User Task (see pp 166 ff) - although they say that there are many potential different implementations, HumanTask is preferred (...and I co-authored these sections, summarizing the position of the group ;-)). Thus, BPMN 2.0 does not refer to any states because its implementation dependent, but each implementation has to define the states - otherwise we run into non-defined situations we are discussion here. Has Activiti these states defined?
