Why do you not store the page name instead of the request Path and then 
returning the page name in the success method ?

As your success method return an Object you can return a String containing the 
requested page name...

@Inject
ComponentResources resources;

...

// Store this in application state
resources.getPageName();


Hope this helps

À : Tapestry users
Objet : Redirect on login

Hi,
 when a user try to connect to my app, it checks if user is logged.
I'm trying to redirect him to page is was trying to access, but I don't
know how to do it in Tapestry way. With plain old sendRedirect of
servlet response it works, but not as clean as it should.
All pages inherits of this page :

    @ApplicationState
    private SimExplorerState applicationState;

    Object onActivate() throws SimExplorerException {
        [...]
        if (!userLogged) {
            String fromURL = requestGlobals.getRequest().getPath(); //
get url being tried
            applicationState.setRequestedURL(fromURL); // save it in
application state of user
            return "Login"; // redirect to login page
        }
        [...]
        return null;
    }

Then in Login :

    public Object onSuccessFromFormLogin() throws SimExplorerException,
IOException {
        [...]
        if (success) {
            [...]
            String fromURL = applicationState.getRequestedURL();
            if (fromURL == null) {
                return elementList;
            }
            //return fromURL.substring(1); // doesn't work, as context
is then included in page name
            requestGlobals.getResponse().sendRedirect(fromURL); // bad
as Tapestry will try to commit data again in response afterwards....
            return null;
        }
        return this;
    }

Thanks for any advice!
