@Override
public RequestCycle newRequestCycle(Request request, Response response) {
return new WebRequestCycle(this, (WebRequest)request,
(WebResponse)response) {
/**
* @see org.apache.wicket.RequestCycle#onEndRequest()
*/
@Override
protected void onEndRequest() {
EntityManagerUtils.disposeEntityManagers();
super.onEndRequest();
}
};
}
