I experienced this too, I started from jpa example. At first the message displayed correct (with no Id). Although it doesn't seems related (and I didn't have time find out exactly the reason) I think it was about messing around with the default language and not including the proper messages_XX.properties in WEB-INF/classes. After correcting that error in my ant script I noticed the ids in the messages were gone, but again, didn't have a chance to confirm if that was in fact the reason. I suspected of that because other related things remained equal. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4111059#...
