Actually I had the same problem when overriding other jbpm objects, so I finally wrote a method like this to get to the target object from the proxies... public static Object narrowProxy(Object maybeProxy) { | if (maybeProxy == null) | throw new IllegalArgumentException("cannot narrow null"); | if ( maybeProxy instanceof HibernateProxy ) { | HibernateProxy proxy = (HibernateProxy) maybeProxy; | LazyInitializer li = proxy.getHibernateLazyInitializer(); | return li.getImplementation(); | //get the real object where the proxy is working on. | //if the proxy is not initialized then it will be initialized here | } else | return maybeProxy; | } | This code has more to do with hibernate, but if someone extends the Jbpm objects then it might be useful View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3979694#...
