Hey, Yeah, I understand.... Well, I added to the entity the following method: | @Override | public boolean equals(Object obj) { | if (!(obj != null && obj instanceof TargetSystem)) | return false; | TargetSystem ent = (TargetSystem) obj; | if (this.targetSystemId.equals(ent)) | return true; | return false; | } | Still getting the 'Validation Error: Value is not valid ' message.... Am I missing anything? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3959547#...
