Minor Description
Using 1.3.0 but still present in 1.3.2 source.
The response i got from the ajax request was :
<?xml version="1.0" encoding="UTF-8"?><ajax-response><header-contribution encoding="wicket1" ><![CDATA[<head xmlns:wicket="http://wicket.apache.org"><script type="text/javascript" src="resources/org.apache.wicket.markup.html.WicketEventReference/wicket-event.js"></script>

And my test is :
tester.assertComponentOnAjaxResponse("updateExpertWizard:form:view:adresse:adresseInner:villeFrancaiseDiv:ville");
It fails in BaseWicketTester.isComponentOnAjaxResponse() :
// Look for that the component is on the response, using the markup id
boolean isComponentInAjaxResponse = ajaxResponse.matches("(?s).*<component id=\"" +
markupId + "\" ?>.*");
failMessage = "Component wasn't found in the AJAX response";
because of the attribut
{ encoding="wicket1" } present in the component tag. The regex must be sweeter like (for example):
"(?s).<component id=\"" + markupId + "\" . ?>.*" (or much much better
