[HtmlUnit] The undefined value has no properties.

[gopal <go...@eb...>]

   We need full javascript functionality to integrate with my =
webapplication.
    I need to test few javascript support sites with htmlunit, if these =
sites pass without any error that's great.
    Is HtmlUnit support full javascript functionality?

Where can i find documentation/exmples for htmlunit use cases.

When i run following code i am getting Exception:

  final WebClient webClient =3D new WebClient();
  final URL url =3D new URL("http://mail.yahoo.com");
  final HtmlPage page =3D (HtmlPage)webClient.getPage(url);
  System.out.println( "Welcome to HtmlUnit " + =
page.getFormByName("login_form").getInputByName("login"));
  final HtmlForm form =3D page.getFormByName("login_form");
  final HtmlSubmitInput button =3D =
(HtmlSubmitInput)form.getInputByName(".save");
  final HtmlTextInput textField22 =3D =
(HtmlTextInput)form.getInputByName("login");
  textField22.setValueAttribute("username");
  final HtmlPasswordInput textField23 =3D =
(HtmlPasswordInput)form.getInputByName("passwd");
  textField23.setValueAttribute("pwd");
  final HtmlPage page2 =3D (HtmlPage)button.click();
  System.out.println(" PAGE :: " + page2.toString());
