Hello,

trunk, r12741.

The following code:

public class ReactDemo {
    public static void main(String[] args) throws IOException {
        java.util.logging.Logger.getLogger("com.gargoylesoftware").setLevel(Level.ALL);
        java.util.logging.Logger.getLogger("com.gargoylesoftware.htmlunit.javascript").setLevel(Level.ALL);
        WebClient wc = new WebClient(BrowserVersion.CHROME);
        try {
            wc.getOptions().setCssEnabled(true);
            wc.getOptions().setThrowExceptionOnScriptError(true);
            wc.getOptions().setJavaScriptEnabled(true);
            wc.setAjaxController(new NicelyResynchronizingAjaxController());
            wc.setJavaScriptTimeout(5000);
            wc.getOptions().setUseInsecureSSL(true);
            wc.getPage("https://react.rocks/");
            wc.waitForBackgroundJavaScript(4900);
        } finally {
            wc.close();
        }
    }

}

causes the following error output:

== CALLING JAVASCRIPT ==
  function () {
      i.check();
  }
======= EXCEPTION END ========

The DOM gets rendered incorrectly (the slide hrefs are not present) and API calls are sent to rollbar.com.

I think I've narrowed it down to the bundled imagesLoaded plugin in https://react.rocks/scripts/bundle.js but I may be wrong.

I don't quite understand what's causing the problem, and as such I've failed to narrow it down to a minimal test case. imagesLoaded, when used by itself, seems to be working for me.

If you would like to refer to this comment somewhere else in this project, copy and paste the following link:

The DOM gets rendered incorrectly (the slide hrefs are not present)

correction: the anchor elements are present, and they have href attributes. With

wc.getOptions().setThrowExceptionOnScriptError(false);

I can get the HtmlAnchor node and call it's click() method. The URL of the page enclosed in the toplevel window will change to that of the URL referenced by the anchor, however the HTTP request to that URL will not be performed (seen using DebuggingWebConnection):

import java.util.logging.Level;
import com.gargoylesoftware.htmlunit.BrowserVersion;
import com.gargoylesoftware.htmlunit.NicelyResynchronizingAjaxController;
import com.gargoylesoftware.htmlunit.TopLevelWindow;
import com.gargoylesoftware.htmlunit.WebClient;
import com.gargoylesoftware.htmlunit.html.HtmlAnchor;
import com.gargoylesoftware.htmlunit.html.HtmlPage;
import com.gargoylesoftware.htmlunit.util.DebuggingWebConnection;

public class ReactDemo {
    public static void main(String[] args) throws Exception {
        java.util.logging.Logger.getLogger("com.gargoylesoftware").setLevel(Level.ALL);
        java.util.logging.Logger.getLogger("com.gargoylesoftware.htmlunit.javascript").setLevel(Level.ALL);
        WebClient wc = new WebClient(BrowserVersion.CHROME);
        try {
            wc.getOptions().setCssEnabled(true);
            wc.getOptions().setThrowExceptionOnScriptError(false);
            wc.getOptions().setJavaScriptEnabled(true);
            wc.setAjaxController(new NicelyResynchronizingAjaxController());
            wc.setJavaScriptTimeout(5000);
            wc.getOptions().setUseInsecureSSL(true);            
            wc.setWebConnection(new DebuggingWebConnection(wc.getWebConnection(), "thingy"));

            HtmlPage p = (HtmlPage)wc.getPage("https://react.rocks/");
            wc.waitForBackgroundJavaScript(4900);


            HtmlAnchor a = (HtmlAnchor)p.getByXPath("//a[@data-reactid=\".0.0.6.0.$mobx-examples.0\"]").get(0);
            System.out.println("MOBX EXAMPLES HREF: " + a.getAttribute("href"));
            a.click();
            Thread.sleep(5000);
            for (TopLevelWindow w : wc.getTopLevelWindows()) {
                System.out.println("TOPLEVEL URL AFTER CLICK: " + w.getEnclosedPage().getUrl());
            }
        } finally {
            wc.close();
        }
    }
}

will print:

[Rhino output here]
MOBX EXAMPLES HREF: /example/mobx-examples
TOPLEVEL URL AFTER CLICK: https://react.rocks/example/mobx-examples

but no request to https://react.rocks/example/mobx-examples will be seen in the listed requests in /tmp/thingy/index.html
