[jira] [Commented] (WICKET-5068) PageParameters missing from re-created Page

["Sven Meier (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/WICKET-5068?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13590890#comment-13590890 ] 

Sven Meier commented on WICKET-5068:
------------------------------------

We could keep the original parameter in a special parameter, so PageProvider is able to recreate an expired page with the same parameters, see attached rudimentary patch.

> WICKET-4594 removes existing PageParameters when re-creating an expired page.
> It does this under the assumption that the parameters are not needed for callback behavior that must not be executed after expiry.
> However PageParameters are needed even without execution of callback behavior.
> In trivial cases, a page cannot be re-constructed successfully without PageParameters e.g. a view page for a customer order needs the order ID from its PageParameters.
> There is a bit of an irony about this. To improve the recovery behavior, i.e. to avoid the dreaded PageExpiryException, one needs to create some client state which is then lost on re-creation after expiry.
