Hi,
new WebClient(); uses IE8 by default.

Please change that to new WebClient(BrowserVersion.CHROME);

Hello all,

I'm using the latest stable release of Htmlunit.

I wrote the following snipet of code to fecth the page
https://exchange.xforce.ibmcloud.com/index.html:


When viewed in Firefox or IE, the source of this page contains this
non-empty div:

*

<div id="wrapper" class="" autoscroll="true" ui-view="" ng-if="!loading"
style="">

<div id="homepage-wrapper">
....other divs 
</div>

</div>

*

The code : 

*
    try {
        WebClient webClient = new WebClient();
        webClient.getOptions().setCssEnabled(true);
        webClient.setCssErrorHandler(new SilentCssErrorHandler());
        webClient.getOptions().setThrowExceptionOnFailingStatusCode(false);
        webClient.getOptions().setThrowExceptionOnScriptError(false);
        webClient.getOptions().setTimeout(5000);
        webClient.getOptions().setJavaScriptEnabled(true);
        webClient.getOptions().setPopupBlockerEnabled(true);
        webClient.getOptions().setPrintContentOnFailingStatusCode(false);
        webClient.waitForBackgroundJavaScript(10000);
        HtmlPage page =
webClient.getPage("https://exchange.xforce.ibmcloud.comindex.html");
        System.out.println(page.asXml());
        } 
                  catch (Throwable err) {
                        err.printStackTrace();
         }
*


When i run this code , i've lots of scripts errors : 

*

and the page.asXml() give me an empty div

*
 <div ng-if="!loading" id="wrapper" ui-view="" autoscroll="true">
</div>

>From the error , I suppose  htmunit not able to run AngularJS scripts on
this page.

Or is the problem with the page itself ?

Why the div is empty? and is there any way of getting its contents even if
there is script errors?

Many thanks.
