This is an issue with Liferay (see
http://issues.liferay.com/browse/LPS-1911)
You can probably fix it by making sure that portlet-name (in
portlet.xml) and the wicketfilter mapping url-pattern are identical
(portlet.xml & web.xml)

Hi,
I am Testing the new Portlet 2.0 with Liferay and have some problems with
Ajax-calls.
I am using wicket 1.4-SNAPSHOT(Revision 741130) and Liferay Portal Standard
Edition 5.2.1 (Augustine / Build 5201 / February 3, 2009).
I have a simple page with one label and one Ajaxlink:
public HomePage(final PageParameters parameters) {
final Label label = new Label("label", new
PropertyModel<Integer>(this, "value"));
label.setOutputMarkupId(true);
add(label);
AjaxLink link = new AjaxLink("link")
{
@Override
public void onClick(AjaxRequestTarget target) {
value = value + 1;
target.addComponent(label);
}
};
add(link);
}
The portlet is shown correctly but when I click the Ajaxlink nothing
happens. In the Ajax-Debug-Log appears the following text:
INFO:
INFO: Initiating Ajax POST request on
http://localhost:8080/web/guest/home?random=0.9410006487742066
INFO: Invoking pre-call handler(s)...
INFO: Received ajax response (84 characters)
INFO:

available
ERROR: Error while parsing response: Could not find root<ajax-response>
element
INFO: Invoking post-call handler(s)...
INFO: Invoking failure handler(s)...
This is the log form Java when the Ajax-Link is clicked:
