Hi, Wicket wraps the beans in serializable proxy, so there is no need to make your services (beans) Serializable. When the bean is type is an interface then Wicket uses JDK Proxy. When it is a class then CGLib is used to create the proxy.
Google for "groovy cglib" problems and you may find the solution. On Wed, Oct 24, 2012 at 1:10 AM, Wujek Srujek <wujek.sru...@gmail.com> wrote: > Hi.
