> Key: WICKET-4001
> URL: https://issues.apache.org/jira/browse/WICKET-4001
> Project: Wicket
> Issue Type: Bug
> Components: wicket

> Reporter: Francis De Brabandere
> Labels: stateless

> See provided quickstart
> I have no idea why but Stateless forms seem to make pages stateful. Tested
> using @StatelessComponent and the StatelessChecker.
> Example mainly from https://cwiki.apache.org/WICKET/stateless-pages.html
> tester.startPage(HomePage.class);
> tester.assertRenderedPage(HomePage.class);
> FormTester form = tester.newFormTester("form");
> form.submit();
> the form.submit() fails with only this info:
> java.lang.IllegalArgumentException: '[Page class = web.web.HomePage, id = 1,
> render count = 1]' claims to be stateless but isn't. Possible reasons: no
> stateless hint, statefull behaviors
