Andrey Rybin commented on CLK-667:
----------------------------------

Interesting reading about this:

http://static.springsource.org/spring/docs/2.5.x/reference/aop.html#aop-atconfigurable


May be add these links to SpringClickServlet  javadoc?

> 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.
