Thanks for your response, to keep track of previous users i am storing it now a variable in business process. Then i assign the task through my class. It works fine. I thought there is a way to track all the users, but couldnt find one so had to do something. Between I have found that jbpm_taskInstances does maintain a list of users assigned to tasks. So i believe even if we know the taskID of previous stage we can get this information. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4128030#...
