I have checked that HtmlUnit does not load part of this page:

https://www.milanuncios.com/mis-anuncios/

When inspected with a browser, the section:

<div class="ma-LayoutBasicMainContent">

Has into a lot of contents. But when loaded by HtmlUnit... it is empty!

I have tried various webClient switches, including

webClient.setAjaxController(new NicelyResynchronizingAjaxController());
webClient.getOptions().setDownloadImages(true);
webClient.getOptions().setCssEnabled(true);
webClient.getOptions().setJavaScriptEnabled(true);
webClient.setJavaScriptTimeout(10000);

But always with same result: The "ma-LayoutBasicMainContent" section is not loaded. This is the code I use:

import com.gargoylesoftware.htmlunit.NicelyResynchronizingAjaxController;
import com.gargoylesoftware.htmlunit.WebClient;
import com.gargoylesoftware.htmlunit.html.*;

class MarnvHtmlUnitTest {

public static void main(String[] args) {

    WebClient webClient = null;

    try {

        final long javascriptTimeout = 10000;

        webClient = new WebClient();
        webClient.setAjaxController(new NicelyResynchronizingAjaxController());
        webClient.getOptions().setDownloadImages(true);
        webClient.getOptions().setCssEnabled(true);
        webClient.getOptions().setJavaScriptEnabled(true);
        webClient.setJavaScriptTimeout(10000);

        String loginURL = "https://www.milanuncios.com/mis-anuncios/";
        System.out.println("Connecting to " + loginURL + " (" + webClient.getBrowserVersion() + ")");

        HtmlPage page = webClient.getPage(loginURL);
        System.out.print("    Waiting for Javascript to complete...");
        long millis = System.currentTimeMillis();
        webClient.waitForBackgroundJavaScript(javascriptTimeout);                              
        System.out.println(System.currentTimeMillis() - millis + " milliseconds");
        if (!page.asText().contains("gestiona tus anuncios")) {
            System.out.println("ERROR!");
            System.out.println(page.asXml());
            System.out.println("EXITING. " + webClient.getWebWindows().size());
            return;
        }

        System.out.println("OK");

    } catch (Exception e) {
        e.printStackTrace();
    }
    finally {
        if (webClient != null)
            webClient.close();
    }
}
}

In case of correct page loading, the page should contain the text "gestiona tus anuncios".
Note that the call to "waitForBackgroundJavaScript" returns inmediately, which for me it's strange... it normaly waits some seconds until the page is completely loaded.

I am using HtmlUnit 2.36.0.

Thank you in advance for your help.

Hi
Yes.. I think it could be related with some Javascript errors during page loading:

Maybe the clue is on the line 338 of Promise.java
Seems that args[0] is not an instance of NativeArray

Ok, i think i have fixed this (the js error). Please check twitter (https://twitter.com/HtmlUnit) for info about a new snapshot build.

Hi!
ok, with the snapshot, the NullPointer disappeared and more sections of the page are loaded.
But... the interesting section are still not loaded... these are the exception I can found:
