Well, I think this is what he's trying to avoid: a client redirect (http
redirect). He wants to delegate the request to a different page using the
same request/response cycle.
You would rather use a ComponentRequestFilter for that: Change the
PageRenderRequestParameters and send them to the next handler.
A simple extract:
public void handlePageRender(PageRenderRequestParameters parameters,
ComponentRequestHandler handler) throws IOException {
// YOUR LOGIC HERE
URLEventContext ctx = new URLEventContext(encoder, new
String[] { "failure" });
// PageRenderRequestParameters params = new
PageRenderRequestParameters("Index", new EmptyEventContext());
PageRenderRequestParameters params = new
PageRenderRequestParameters("Index", ctx);
handler.handlePageRender(params);
}
