2 things: 1.) The question "if somebody sees problems with the query refereing to the process instance id order" is related to the application domain, so I think it is right in this forum. 2.) I can not post any question to the hibernate forum, because I don't have credits there. So I can only hope somebody has an idea here, otherwise I think I can only leave it as open issue for the moment :-/ View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4104235#...
