Stateless Apache Wicket stateless pages/requests

Question

So I was reading another question under the Wicket tag comparing Apache Wicket and Apache Click. A concise explanation, in my opinion. I am more familiar with the Wicket world t

Answer 1

I prefer to check that in test.

so each test for stateless page overrides

getStatelessWebPage()

which by default returns null.

then in basic test I have generic test that visits all components on page and check whether component is stateless or not

@Test
public void checkForStateless()
{
    StatelessWebPage statelessPage = getStatelessWebPage();
    if (statelessPage != null)
    {
        Page page = (Page)statelessPage;
        if (!page.isPageStateless())
        {
            //find the reason
            Component statefulComponent = page.visitChildren(Component.class, new StatelessChecker());
            if (statefulComponent != null)
            {
                fail("Stateless page contains stateful component ["
                     +statefulComponent.getClass().getName()+" : "
                     + statefulComponent.getMarkupId() +"]");
            }
        }
    }
}

and

class StatelessChecker implements IVisitor
{
    @Override
    public void component(Component component, IVisit iVisit)
    {
        if (!component.isStateless())
        {
            iVisit.stop(component);
        }
    }
}
