When we get a process instance or execution from executionService, the instance couldnot automaticly notice when the related record in database being updated.  Because the session of hibernate has been closed. So commonly, after we do some operations likes signal, we should re-get the process instance or execution from executionService, then we could get the real state.  Otherwise what we get will be always the 'OLD' data. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/546924#546924] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
