Description

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
