the implementation of js failure handler does not work for the case
(from tracing the js codes)
i guess it is because the "ajax session expire exception" thrown to the
client contains "redirect" path information, by which wicket just use this
redirect path and ignore the failure handler
and i have come up a quick solution:
override the method WebRequestCycleProcessor (i.e. need to register your
custom processor)
<code>
public IRequestTarget resolve(RequestCycle requestCycle,
RequestParameters requestParameters) {
try {
return super.resolve(requestCycle, requestParameters);
} catch (RuntimeException re) {
if (re instanceof PageExpiredException) {
if (((WebRequestCycle)
requestCycle).getWebRequest().isAjax()) {
// return a custom ajax request that only contains
failure handle js
/*
AjaxRequestTarget art = new AjaxRequestTarget(null);
art.appendJavascript(your failure handler js);
return art;
*/
}
}
throw re;
}
}
</code>
