Martin,
I had to modify your example to get it to work, as request.getUrl()
actually returns a new Url instance when it's called. Here's what I
settled on:
@Override
public IRequestHandler mapRequest(Request request) {
Request requestToMap = request;
if ((request instanceof WebRequest) && !((WebRequest) request).isAjax()) {
PageComponentInfo info = getPageComponentInfo(request.getUrl());
if (info != null) {
Url url = request.getUrl();
url.removeQueryParameters(info.toString());
requestToMap = request.cloneWithUrl(url);
}
}
return super.mapRequest(requestToMap);
}
Does anyone see any issues with this approach?
Thanks!
-Allen
