If you are have a Form (a wicket one) inside a Page, then you can do your 'submitTheForm()', because a simple 'submit()' suffice to post the form. If your 'page' parameter you want to retrieve is bound to an Wicket FormComponent (even an HiddenField), then you can retrieve it server side and do a setResponsePage; you just have to get the right Page class from the param and maybe construct your PageParameters also...
Hope this helps, Sebastien.
