Once the thread finds a sub processed had ended, it could send a message to main process.  The problem is you must control thread's lifecycle all be yourself, and have to prepare to handle the exception occured on process executing.  It is mostly like a real time monitor management system.  If you really want to do this, please make a good plan first. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/538625#538625] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
