do like the message says:
You can switch to JDK based serialization by
calling: wicket.util.lang.Objects.setObjectStreamFactory(new
IObjectStreamFactory.DefaultObjectStreamFactory()) e.g. in the init
method of your application
i think there is a bug in our optimized serialization where it doesnt handle
proxies properly yet

Hi all,
we received the following exception within a WebPage using an injected

shouldn't happen
Here is the applicationContextSnippet:
...
<bean id="mergedSessionFactory"
class="de.ponton.box.core.bootstrap.DynamicSessionFactoryBean"
singleton="true">
<property name="dataSource">
<ref bean="dataSource" />
</property>
....
we are subclassing LocalSessionFactoryBean from spring:
...
public class DynamicSessionFactoryBean extends LocalSessionFactoryBean
{
...
and here is the code snippet:
....
@SpringBean
SessionFactory sessionFactory;
....
This has worked with Wicket 1.2.5...
Any ideas?
