I am trying to get the component inside an advice and if the page
invoked isextends "SecurePage", then I have to check the security
credentials on that request.
A way better way of doing it is to implement a ComponentEventRequestFilter
and contribute it to the service ComponentEventRequestHandler. Take a look
at the graph in the end of
http://tapestry.formos.com/nightly/tapestry5/guide/request.html to have a
better look at how Tapestry processes requests.
A typical cross-cutting concern which is best served by an advice.
Advice is for services, not pages and components.
By the way, looking at your advice, there's the ComponentEventLinkEncoder
service that provides methods like PageRenderRequestParameters
decodePageRenderRequest(Request request) to deal with extracting the page
name from a request.
