BaseWicketTester#clickLink does not "simulate" ajax request

[Gerolf Seitz]

hi,
it seems like BaseWicketTester#clickLink does not generate an ajax request.
excerpt:

if (linkComponent instanceof AjaxLink)
        {
            // If it's not ajax we fail
[0]        if (isAjax == false)
            {
                fail("Link " + path + "is an AjaxLink and will " +
                    "not be invoked when AJAX (javascript) is disabled.");
            }

            AjaxLink link = (AjaxLink)linkComponent;

            setupRequestAndResponse();

[1]         // getServletRequest().addHeader("Wicket-Ajax", "Yes");

[2]        RequestCycle requestCycle = createRequestCycle();
            if (requestCycle.getRequest() instanceof WebRequest &&
                !((WebRequest)requestCycle.getRequest()).isAjax())
            {
                fail("this is no ajax request");
            }


[0] only uses the parameter for the check, not the actual request

if [1] is uncommented, several other tests fail, due to assuming that there
is an ajax request, when actually there is none

[2] checks whether the current WebRequest is an ajax request. with [1] being
commented, the test fails with "this is no ajax request".

note: [1] and [2] were added by me and cannot be found in the code in trunk



either i'm missing something, or a lot of tests involving ajax are seriously
broken.
in any case, this should be clarified before releasing RC2.

any comments?
