this help. but it still not allow me to cast it to the real object. so after looking around, this is the solution that i found : | if (node instanceof HibernateProxy) { | node = (Node) ((HibernateProxy) node).getHibernateLazyInitializer() | .getImplementation(); | } | then i can do something like : | if (node instanceof TaskNode) { | taskNode = (TaskNode) node; | } | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3960593#...
