What you need to do here is pass the pageId and pageMap name as page
parameters. And then lookup the page using session.get(). But this
approach is somewhat fragile. If someone bookmarks the url and then
pastes it to browser, the previous page will not be there.
Anyway, if you are using current 1.3, there is easier solution. Just
mount the page using HybridUrlCodingStrategy (and make sure it has
default constructor - is bookmarkable). Then pass the page reference
to page constructor (not the default one).
Even if you create the page using new MyPage(myPrevPage) and do
setResponsePage(myPageInstance) the url will still be bookmarkable.
But will also contain page instance number so it will look like
/my/mount-path.3 (3 being the page instance id).
