    a4j + session expired -> blank page (Firefox bug?)

    Jaroslaw Ledzion Newbie

      My env:
      Tomcat 5.5
      Facelts 1.1.12
      MyFaces Tomahawk
      JSF 1.2
      A4J 1.1.0

      I've got an application with form-based authentication (LDAP realm).
      On one page there is a form with two selects. If first select has changed second one should be rerendered so the code is:


      <h:outputText value="#{app['header.category']}"/>
       <h:selectOneMenu value="#{asset.searchAsset.category}" title="IdCategory">
       <f:selectItem itemValue="-1" itemLabel="#{app['global.noneSelected']}"/>
       <f:selectItems value="#{asset.categories}"/>
       <a4j:support event="onchange" reRender="idSubcategorySearch" />
       </h:selectOneMenu>
      
       <h:outputText value="#{app['header.stand']}"/>
       <h:selectOneMenu id="idStandSearch" value="#{asset.searchAsset.stand}" title="IdStand">
       <f:selectItem itemValue="-1" itemLabel="#{app['global.noneSelected']}"/>
       <f:selectItems value="#{asset.stands}"/>
       </h:selectOneMenu>
      
      
      Everything works fine until session expires...than when user change value of the first select blank page is shown.
      The problem exsists only in Firefox...IE and Opera works fine showing login page.
      Logs from server are:

      Does any one know how to fix it in Firefox?
      BTW:
      I've tried to use A4J.AJAX.onExpired but couldn't make it work at all:-(

      <script type="text/javascript">
       A4J.AJAX.onExpired = function(loc,expiredMsg){
       alert('custom expired');
       };
       </script>


      regards.
