jQuery 1.4 AJAX requests broken if using Richfaces
--------------------------------------------------

                 Key: RF-8282
                 URL: https://jira.jboss.org/jira/browse/RF-8282
             Project: RichFaces
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: browser compatibility, third-party
    Affects Versions: 3.2.2
         Environment: Windows XP, Internet Explorer 7.0
Mac OS , Firefox 3.5.7
            Reporter: Oleg T
            Priority: Critical

If external jQuery 1.4 is used on the same page as richfaces, all asynchronous requests are not working in Internet Explorer (confirmed version 7) with very peculiar error message: "This method cannot be called until open method has been called". jQuery alone works as expected.
Here's the test code to reproduce the problem:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
      xmlns:h="http://java.sun.com/jsf/html"
      xmlns:f="http://java.sun.com/jsf/core"
      xmlns:a4j="http://richfaces.org/a4j">
<f:view>
<head>
    <meta http-equiv="Content-type" content="text/html; charset=utf-8" />
    <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js"> </script>
</head>

<body id="wide">

<script language="JavaScript" type="text/javascript">
    jQuery(document).ready(function() {
            jQuery.ajax({
                url: '/',
                cache: false,
                //context: this,
                success: function(html) {
                    alert('success!');
                },
                error: function (XMLHttpRequest, textStatus, errorThrown) {
                    alert('failed: ' + errorThrown.message);
                }
            });
    }
 );
</script>

<a4j:form style="display:none">
    <a4j:commandLink id="saveScreenModeLink" actionListener="#{user.saveScreenMode}" />
    <h:inputHidden id="screenMode" value="#{userInfoBean.screenMode}"/>
</a4j:form>
</body>
</f:view>
</html>  

This code works fine in Safari 4 and FF 3.5, but throws http://grab.by/1Sm0 in IE7.
If you remove a4j tag it works in IE7 as well.
