AbstractTransformerBehavior does not support ajax in wicket 1.5.1
Hi,
Using ajax to update a component that has an AbstractTransformerBehavior
attached throws a ClassCastException (see below). I can only assume that
this is not intentional?
Root cause:
java.lang.ClassCastException:
org.apache.wicket.ajax.AjaxRequestTarget$AjaxResponse cannot be cast
to org.apache.wicket.request.http.WebResponse
