Martin Grigorov commented on WICKET-5693:
-----------------------------------------
> The concern is that even with setVersioned(false) on Page level, we get two
> page versions not one.
Create a quickstart and attach it to a new ticket with detailed description how
to reproduce this.
> setVersioned(false) should force single Page Version

> Key: WICKET-5693
> URL: https://issues.apache.org/jira/browse/WICKET-5693
> Project: Wicket
> Issue Type: Bug
> Components: wicket
> Affects Versions: 6.16.0
> Environment: All
> Reporter: Bernard
>
> After a form submit, we want the browser's back button to show the page
> before the form not the form page. That is a business requirement to prevent
> double submits.
> A web application can, via the use of Post-Redirect-Get, respond with the
> same URL as the form page's request URL, and let the browser history replace
> the form page with the form submit result page.
> In Wicket, we can attempt to achieve this behaviour by using the same page
> class for form and response - replacing a form panel with a response panel.
> Still Wicket creates multiple versions of the page which show as version
> numbers in the URL. To fix this, we call setVersioned(false).
> But still, the page is served with different URLs. This needs to be fixed in
> some way.
> We need full core framework support for this, without having to code
> workarounds. We have coded workarounds in the past, but these were broken by
> subsequent Wicket releases, even minor releases.
> We might need the URL to be version-free because the page's initial URL,
> being bookmarkable, would not have a version number. The only limitation
> should be the case where the browser does not have a cookie for the site,
> where the first page visited is the form page, having jsessionid in the URL.
