To view the discussion, visit: http://community.jboss.org/message/613608#613608 -------------------------------------------------------------- Thank you! I have tried this method, #but after the intercepted human task was completed, the Ksession couldn’t know it, the state of the task was still 1, and I couldn’t continue with the other tasks. How can I solve this problem?
