In cases like this where an OptimisticLockException occurs, does Seam have no way of using exceptions.xml to handle this fact and display a nice error message? I've exhausted all my resources and don't know where else to turn apart from this board...please, if somebody knows how to use exceptions.xml to catch it, let me know... If you need any more info on the issue, I can provide it... Thanks. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4009225#...
