Hi,

this is a great tool even I hit this error. I am trying to access a web site: http://finance.yahoo.com/lookup and use htmlunit to change a value in the input field of the form, then click a button from that form and get the second page back. 

The html page snippet like below:


~~~~~~~~~~~~~~~~~~~~~~~
<div class="bd">
    <form accept-charset="UTF-8" method="GET" action="/q" name="quote" id="quote" class="get-quotes has-button">
        <i class='magIcon'></i>
        <input placeholder="Enter a ticker or company name" type="text" autocomplete="off" value="" name="s" id="txtQuotes" class="get-quotes-box">
        <input type="hidden" autocomplete="off" value="1" name="ql" id="get_quote_logic_opt">
        <input type="submit" class="get-quotes-button rapid-nf Bdrs"  value="Go" id="btnQuotes"> 
    </form>
...
</div>
~~~~~~~~~~~~~~~~~~~~~~~

my code is like below:

~~~~~~~~~~~~~~~~~~~~~~~
try {
		   final WebClient webClient = new WebClient(BrowserVersion.INTERNET_EXPLORER_11);
		   final HtmlPage page1 = webClient.getPage("http://finance.yahoo.com/lookup");

           // get button from the page
		   final HtmlSubmitInput button = page1.getFirstByXPath("//input[@id='btnQuotes']");
		   
           // get text field from the page
		   final HtmlTextInput textField = page1.getFirstByXPath("//input[@id='txtQuotes']");
		   
		   // Change the value of the text field
		   textField.setValueAttribute("google");

		   // Now submit the form by clicking the button and get back the second page.
		   final HtmlPage page2 = button.click(); // it fails here
		   page2.save(myfile);
	   }
       catch (IOException e){    	   
       }
~~~~~~~~~~~~~~~~~~~~~~~       

It fails at line of "final HtmlPage page2 = button.click();". 
It seems it is able to get to the second page URL correctly, which means button click is functionning well and text field filling is okay, but fails at later process.
The second page URL is like this (see below from exception messages):
http://finance.yahoo.com/q?s=GOOG

I have searched your bugs Mailing Lists, someone reported a similar issue at this number:
#1481 HtmlUnit can't open http:mailtrap.io (func postMessage is missing)  and this ticket was fixed and closed. Not sure why I am hitting it again. I am using latest downaloaded version of htmlunit-2.18.

Many thanks for your help.

Tommy
