Re[2]: Page Name
Posted by Max Grigoriev <da...@mail.ru>.
I created MyEngine to redirect request to tapestry pages after post
form and to disabled double click and back buttons.
Redirect after post I made overloaded public void
renderResponse(IRequestCycle cycle, ResponseOutputStream output) in
MyEngine.
public void renderResponse(IRequestCycle cycle, ResponseOutputStream output)
throws ServletException, IOException {
String method = cycle.getRequestContext().getRequest().getMethod();
final IPage page = cycle.getPage();
setPageToRedirect(page.getPageName());
final Visit visit = (Visit) getVisit();
if ("POST".compareToIgnoreCase(method) == 0) {
setRedirectMe(true);
if (visit != null)
visit.setRedirect(true);
} else {
setRedirectMe(false);
if (visit != null)
visit.setRedirect(false);
super.renderResponse(cycle, output);
}
}
to solve second task i create a cookie and send it to a client, then in public boolean
service(REquestContext context) i compare cookie and key in visit
object. If they are not the same, i redirect to this page. In this
case i don't want to invoke AbstractEngine.service. But i don't know
to which page i should redirect, that's why i have to know page name
from HttpServletRequest

Actually, the page name is parsed by the appropriate engine service
implementation on every request and is available in the RequestCycle
object - which is merely an abstraction of the HTTP request and session.
requestCycle.getPage().getPageName();
No?

You can't (assuming you mean HttpServletRequest). Why would you want to?

Why would you want to do this? I'm just curious, as there really is no
need for this if you are staying within the confines of Tapestry itself.
