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.
