Thank you very much for posting that. I know I added a sort of ProcessInstanceCreateLog.hbm.xml to log when a process was created. And it worked well also. At the time, I didn't want to modify the JBPM source code because we would then have to do it every time we update. You're giving me motivation to go ahead and do it though.
