bernd, if you want this feature, you can implement a hook. so that by default, the jbpm behaviour remains as is (read: no event listening)
and that in your configuration file, you can plug in an event listener in the configuration file.
if this is added with test cases and docs, i think it will also be ok for thomas. but i'll ask him to comment.
thomas says
yes, that's ok.
Okay, wrote some lines about what we did now here: http://www.bpm-guide.de/2008/12/06/easily-generate-bam-events-wih-jbpm/. Sorry for not giving more details,to limited time...
