Refreshing the form does not work on IE

Question

We are developing a standard Struts 1.3/Hibernate application, running on TomCat server.
The application is used inside ALUI using 2 portlets: a menu portlet, with some additional common fields an options, and a content portlet, where the page selected in menu is presented.
When you click in the menu, we have to post the menu form, and also the content portlet, using the bellow script:
function menuClick(pagina) {
     var id = parseInt("$PORTLET_ID$");
     var portlet = null;
     principalMenuForm.pagina.value = pagina;
     if (id > 0) {
          portlet = PTPortlet.getPortletByID(id);
          principalMenuForm.method = 'POST';
          if (portlet != null) {
               portlet.formPostRefresh(principalMenuForm);
          portletPagina = PTPortlet.getPortletByName("Portlet - Sistema XXX");
          if (portletPagina != null) {
               portletPagina.refresh();
     } else {
          form.submit();
When we run on a Mozzilla browser, the refresh works correctly, but after painting the new contents, the application hangs for around 5 seconds and after that works correctly.
When running on IE, the page keeps waiting for content, and after some time becomes blank. If you navigate to the page again (press Enter in address fiield), the page is correctly rendered and works perfectly.
Does anyone have any hint around this?

Answer 1

this is a very long shot, but try this
principalMenuForm.method = 'post';
