      Description

      SpringClickServlet currently injects beans only for newly created page instances. This works well for stateless pages but not for stateful pages that have been serialized/deserialized. After a stateful pages has been deserialized, the bean references are null.

      ClickServlet provides the #activePage hook which can be used to re-inject beans after deserialization.

      Unfortunately this fix will only apply to "Click created pages with bean injection" or option 3 described in the SpringClickServlet. Option 1 and 2, where Spring itself creates the Click pages and inject beans, does not work after deserialization because Spring does not re-initialize the page. Its possible to inject serializable proxies instead of direct references, however that could mean relying in byte code generation.
