Description

The underlying issue is that WebRequestCycle.isAjaxRequest returns true but RequestCycle.find(AjaxRequestTarget.class) returns null anyway, because the current request handler is a ListenerInterfaceRequestHandler.

This leads to
java.lang.NullPointerException
at org.apache.wicket.markup.html.form.AutoLabelResolver$AutoLabelMarker.updateFrom(AutoLabelResolver.java:222)
