[Htmlunit-user] TypeError

[<Ale...@ag...>]

Hello

I get the following exception, while executing the following testcase. The
exception occurs after
final HtmlPage page2 = (HtmlPage)button.click();

Just an idea: Is the access of attributes of the style JavaScript object not
supported ?

I attach the javascript module menu_.js

======= test case ========
	public static void main(String[] args) throws Exception {
		// Internet Explorer 6.0.*
				final BrowserVersion browserVersion = new
BrowserVersion("Microsoft Internet Explorer",
					"4.0 (compatible; MSIE 6.0; Windows
NT 5.1; SV1; .NET CLR 1.1.4322)",
					"Mozilla/4.0 (compatible; MSIE 6.0;
Windows NT 5.1; SV1; .NET CLR 1.1.4322)", "1.2", 6F);
		final WebClient webClient = new WebClient(browserVersion);
		final URL url = new URL(START_URL);
		final HtmlPage page1 = (HtmlPage)webClient.getPage(url);

		final HtmlForm form = page1.getFormByName("logonform");
		final HtmlTextInput textField =
(HtmlTextInput)form.getInputByName("userId");
		// Change the value of the text field
		textField.setValueAttribute(USER_ID);

		final HtmlPasswordInput password =
(HtmlPasswordInput)form.getInputByName("password");
		password.setValueAttribute(PASSWORD);

		final HtmlButton button =
(HtmlButton)form.getButtonsByName("submitButton").get(0);

		// Now submit the form by clicking the button and get back
the 
		// second page.
		final HtmlPage page2 = (HtmlPage)button.click();
		
		System.out.println(page2.asXml());

		...
	}
