Hi Tom, of course not :-) But the jbpm.cfg.xml is the same, yes. So the critical points, the transactions configuration, is exactly the same. Important is to start a second jbpmContext inside a action (so a "nested" jbpmContext) to reporudce the first error I described. Maybe it depends on the hibernate version if you can not reporduce it? Maybe they have changed the commit() method, but sounds strange to me.... View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4046721#...
