-------------------------------
Summary: 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.
