  2. Javascript error help please[ Go to top ]

    Its giving the error because its not able to find resourceForm object on the jsp. Add "name" and "type" attributes in <html:form> it would work:

    <html:form name="refreshForm" type="presentation.form.RefreshForm"
    action="/refresh.do" method="post" onsubmit ="submitPage()">

  3. lost document object[ Go to top ]

    We have experienced the same proplem with:
    XP prof + IE 6
    Nevertheless, it works fine in W2K+IE6 and firefox.
    Believe the there is a bug in ActiveX in XP.

    What is your browser?

    Try a workaround
