    Revision 1.4  2006/02/16 10:36:34  sde
    delete function addBreadCrumb (define in CommonScript.js)

    Revision 1.3  2006/02/06 15:37:57  sde
    correct function addBreadCrumb: rename id breadcrumb into breadCrumb

    Revision 1.2  2005/12/12 14:25:55  sde
    change the home page link from portalHomePage.jsp to index.jsp
