Whatever it turn to wait or end state, ther service will return and we could get the process instance. One request, One response. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/540280#540280] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
