Hello,

We are using HtmlUnit 2.33 for dealing with Javascripted web pages and get the text on the pages, this works very well! There are, however, a set of web pages (links below) that i cannot get the text from. HtmlUnit logs a bunch of errors and throws a NPE in EventHandler constructor line 50.

Being new to HtmlUnit, i, of course, have absolutely no idea what the root of the problem is, but i'm filing a bug instead of a mailing list message due to the NPE i got.

How can we get the final recipe text which i loaded via AJAX?

Thanks!

Code:
~~~
    BrowserVersion version = new BrowserVersion.BrowserVersionBuilder(BrowserVersion.CHROME).build();
    WebClient client = new WebClient(version);

    client.getOptions().setThrowExceptionOnScriptError(false);
    client.getOptions().setCssEnabled(false);
    client.getOptions().setJavaScriptEnabled(true);
    client.getOptions().setDownloadImages(false);
    client.getOptions().setThrowExceptionOnFailingStatusCode(false); 
    client.getOptions().setPrintContentOnFailingStatusCode(false);
    client.getOptions().setUseInsecureSSL(true);
    client.getOptions().setRedirectEnabled(false);
    client.setJavaScriptTimeout(20000);
    page = client.getPage(url);
    synchronized(page) {
      try {
        page.wait(20000);
      } catch (Exception e) {}
    }
    client.waitForBackgroundJavaScript(10000);
