> The 'Wicket-Ajax' header is always missing when using BaseWicketTester, even when the request should be an AJAX request.
> The specific case we have is an AjaxLink that, when clicked, shows a modal window. We call BaseWicketTester's clickLink(String) method to simulate clicking the link. The link's onClick(...) method is called with an appropriate AjaxRequestTarget; however, ModalWindow's onBeforeRender() tests whether the request is an AJAX request (using ((WebRequest)getRequest()).isAjax()) and, if it's not, hides the content panel.
> The problem is that the isAjax() call tests whether the HttpServletRequest's 'Wicket-Ajax' header is present and 'true'; when running this code with BaseWicketTester, the header is never there, and so the modal window's content is never shown.
> We have worked around the problem by overriding clickLink(String, boolean) and setupRequestAndResponse() as follows:
>     private boolean m_handlingAjaxRequest = false;
>     
>     @Override
>     public synchronized void clickLink(String path, boolean isAjax)
>     {
>         m_handlingAjaxRequest = isAjax;
>         super.clickLink(path, isAjax);
>         m_handlingAjaxRequest = false;
>     }
>     
>     @Override
>     public synchronized WebRequestCycle setupRequestAndResponse() {
>         WebRequestCycle result = super.setupRequestAndResponse();
>         if (m_handlingAjaxRequest) {
>             // Set AJAX header.
>             getServletRequest().addHeader(
>                         "Wicket-Ajax", "true");
>             // *Don't* copy it to the response, even though
>             // MockWebApplication's setupRequestAndResponse() does.
>         }
>         return result;
>     }
> (I found that if I copied the 'Wicket-Ajax' header to the response, as done by MockWebApplication's setupRequestAndResponse(), it caused all AJAX clicks to misbehave.)
> Hence, it would seem that if BaseWicketTester's clickLink(String, boolean) method were modified to set the 'Wicket-Ajax' header as appropriate, modal windows -- and, presumably, any other things that rely on the request returning true from isAjax() -- would work as expected.
