Spring servlet should support stateful pages with transient beans
-----------------------------------------------------------------
Key: CLK-667
URL: https://issues.apache.org/jira/browse/CLK-667
Project: Click
Issue Type: Bug
Components: extras
Affects Versions: 2.1.0
Reporter: Bob Schellink
Assignee: Bob Schellink
Fix For: 2.2.0
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.
