javascript error in extendedDataTable

[granite2009]

I copied the demo extendedDataTable component into a standalone page. Only filter action is not working interactively like the demo. Further digging reveals a javascript error that prevents Ajax from working.
The error is "elt is null or not an object".
Is there a work around for the filter event to work interactively.
My code is listed below.

<?xml version="1.0" encoding="iso-8859-1" standalone="yes" ?>
<jsp:root xmlns:jsp="http://java.sun.com/JSP/Page" version="2.0"
xmlns:ui="http://java.sun.com/jsf/facelets"

xmlns:rich="http://richfaces.org/rich">
<jsp:directive.page contentType="text/html;charset=utf-8" />
<f:view>
<h:form>

<rich:extendedDataTable value="#{distListBean.lists}" var="cap"
id="table" width="580px" height="400px">

<rich:column sortable="true" sortBy="#{cap.owner}"
filterBy="#{cap.owner}" filterEvent="onkeyup" width="170px"
rendered="true" label="Owner">
<f:facet name="header">
<h:outputText value="Owner" />
</f:facet>
<h:outputText value="#{cap.owner}" />
</rich:column>
</rich:extendedDataTable>
</h:form>
</f:view>
</jsp:root>

describe environment please more carefully, (versions, browsers).

[granite2009]

Vresion 3.3.2
Browser Firefox 3.5, IE7
Tomcat 6 on Windows
Oracle 10G
elcipselink persistence
Is that enough?

Now my javascript error is gone but ajax filter is still not working.

the code looks ok.. and as you could see at http://livedemo.exadel.com/richfaces-demo/richfaces/extendedDataTable.jsf it's the same.

could you please also check a4j:log. if there are any errors?
