A bookmarkable page link is a bit different because that link shouldn't throw an exception
or redirect to something i think. That one should just base his visibility on the constructor params
And that is done by: boolean isActionAuthorized(Component component, Action action);
and then the RENDER action. The only problem is that you can't get the params back out
(there is no getParameters() and getPageClass())
But this is pretty solveable by making your own simple BookmarkablePageLink
The setResponsePage(Class [, PageParams] ) is different there you can't easily come between something
If you want to catch if you can construct that page after the redirect. I don't know what the best way would be
currently this is the code:
public void respond(RequestCycle requestCycle)
{
if (pageClass != null)
{
if (requestCycle.getRedirect())
{
IRequestCycleProcessor processor = requestCycle.getProcessor();
String redirectUrl = processor.getRequestCodingStrategy()
.encode(requestCycle, this).toString();
requestCycle.getResponse().redirect(redirectUrl);
}
else
{
// Let the page render itself
getPage(requestCycle).renderPage();
}
}
}
so in the if (requestCycle.getRedirect ()) we could call something. So that we fail early... instead of only after the redirect.

Please note that I am not pleading for doing authorization on pages
based on page parameters.
I am looking for a simple uniform wicket-provided way to protect pages
that have page parameters. Specifically for two use-cases:
setResponsePage(MyProtectedPage.class, parameters);
and
new BookmarkablePageLink("fooLink", MyProtectedPage.class, parameters);
Right now support for that is non existent or only possible with hacks
as workarounds.
