Re: AjaxTabbedPanel, AjaxLazyLoadPanel and back button

[Rodrigo De Castro <ro...@sacaluta.com>]

I solved this problem turning off the browser's cache for this page. So I
added the following override method and now it works just fine:

    @Override
    protected void configureResponse() {
        super.configureResponse();

        final WebResponse response = getWebRequestCycle().getWebResponse();
        response.setHeader("Cache-Control", "no-cache, max-age=0,
must-revalidate, no-store");
    }

Please let me know if there is another (better) solution.
