Martin Grigorov commented on WICKET-5539:
-----------------------------------------

In Wicket 7.x it is possible to re-create the page, pass (all) request 
parameters as page parameters, and depending on 
org.apache.wicket.Component#canCallListenerInterfaceAfterExpiry() and 
org.apache.wicket.settings.PageSettings#getCallListenerInterfaceAfterExpiry() 
decide whether to execute the action (onClick, onSubmit, etc.).

The change is:
https://git-wip-us.apache.org/repos/asf?p=wicket.git;a=commit;h=a1f862629c223b675a31c4ba9fb7e07c27279090

> There is a bookmarkable page mounted, for example, to:
> /page/${entityId}
> This page contains StatelessForm.
> Submitting of form after session expire lead to following:
> org.apache.wicket.core.request.mapper.MountedMapper invokes 
> AbstractBookmarkableMapper.processListener to obtain IRequestHandler to 
> handle submitting of form. 
> But there is cleaning of PageParameters within processListener on line 256 
> (Wicket 6.14) which cleaning "entityId" parameter as well and created page 
> finally has no "enityId" and (in our case) redirects to 404.
> I see that this cleaning of page parameters was implemented due to 
> Wicket-4594. But I think, just checking for pageId is unsufficient, because 
> pageId might be not null, but actual page may be already expired and new 
> instance should be created.
