Wicket integration - Conversation lifecycle is broken when onPageAttached() is overridden.
------------------------------------------------------------------------------------------

                 Key: JBSEAM-4808
                 URL: https://issues.jboss.org/browse/JBSEAM-4808
             Project: Seam 2
          Issue Type: Bug
          Components: Wicket
    Affects Versions: 2.2.2.Final
         Environment: MAC OS X
Java 1.6.0_24
JBoss AS 5.1.0.GA
JBoss SEAM 2.2.2.FINAL
            Reporter: Rob Shepherd


Primarily - see the seam framework forum post.

Under the hood of course, onPageAttached() will have been instrumented to:

onPageAttached100() and the original method name then providing a SEAM request lifecycle wrapper, to perform injection and other interceptor functions around the original method content.


It looks like the seam manager has not yet begun delivering the request and retrieved the conversation ID from the previously rendered 
page's page map and switched the conversation.

In the failure mode - I'm unclear how a conversationally scoped re-injected instance can exist when the current conversation ID is seen to change.

The original use-case for overriding the onPageAttached() was - when re-rendering page instances from the page map - to detect changes in other injected session-scoped context variables and mark a page as expired if changes have occurred - or proceed if no changes have occurred.

Any @In-jected conversational bean is replaced by a new instance - even if (later in the request) the conversation ID seems to revert back to the proper ID.
