[Htmlunit-user] Urgent: JavaScript: getFrameset(""); returning null

[Bhupesh R. S. <bhu...@vi...>]

I am migrating from HttpUnit to HtmlUnit. I am trying to login to my
application from HtmlUnit.
=20
Here is the test case.
=20
       public void testHtmlUnit() throws IOException=20
       {
           WebClient wc =3D new WebClient();
           wc.setRedirectEnabled(true);
           URL url =3D new
URL("http://localhost:8080/abc/abc_frameset.jsp");
           HtmlPage page =3D (HtmlPage)wc.getPage(url);
          =20
           HtmlForm form =3D page.getFormByName("mainForm");
           HtmlSubmitInput loginButton =3D
(HtmlSubmitInput)form.getHtmlElementById("loginButton");
           HtmlTextInput username =3D (HtmlTextInput)
form.getInputByName("j_username");
           HtmlPasswordInput password =3D (HtmlPasswordInput)
form.getInputByName("j_password");
           username.setValueAttribute("zdpm_admin");
           password.setValueAttribute("zdpm_admin");
           HtmlPage page2 =3D (HtmlPage) loginButton.click();
           //System.out.println(page2.toString());
          =20
       }
=20
When I run it, I get the following exception.

The line 148 of navbar.js has the following code. hideLeftnav() method
is called from the onLoad event.
=20
146    function hideLeftnav() {
147        var bottom =3D getFrameset("bottom") ;
148        bottom.cols=3D"0,*";
149    }
=20
my frameset looks like this.
=20
<frameset id=3D"application" title=3D"Application" rows=3D"60,0,*"
          framespacing=3D"0"  frameborder=3D"1" >

               marginwidth=3D"0" marginheight=3D"0" frameborder=3D"0"
scrolling=3D"auto">
        <frame class=3D"workArea" id=3D"workarea" name=3D"workArea"=20
               marginwidth=3D"0" marginheight=3D"0"=20
               scrolling=3D"auto" frameborder=3D"0" src=3D"<%=3D =
workarea %>">
  </frameset>
</frameset>

Apparantly getFrameset("bottom"); is returning null. But when I run it
from the browser (IE 6), it is working fine. It is working even from the
HttpUnit test case. Can anyone explain why this is happening.
=20
also i am getting lot of warnings and info's on my console. some of them
include

I have explicitly added webClient.setRedirectEnabled(true); in my code.
but why i am still getting the INFO: Redirect requested but
followRedirects is disabled.
=20
What does the warning Expected content type of text/javascript but got
[text/html] means.
