Hi all,
i have some problems to understand the redirecting mechanism of wicket.
When i try something like this:
public class Testing extends WebPage {
public Testing() {
add(new Link("go") {
public void onClick() {
getResponse().redirect("/");
}
});
}
}
I get that:
javax.servlet.ServletException: Internal Error: Could not redirect to
exception error page. Was trying to display exception for page [Page
class = Testing, id = 0]:
wicket.WicketRuntimeException: Already redirecting to '/'. Cannot
redirect more than once

So i found out that response.redirect should not be used by the user
(btw: why isn't it private when it should not be used?).
Then i found out you can redirect with
setResponsePage(new RedirectPage("/"));
But the problem is that there is a HTML-Page with a Meta-Refresh send.
Is there a possibility to use HTTP-Header Location with wicket?
Thanks,
Dave
