richfaces data-table error - ajax

Question

I am new to richfaces.
I have a problem with rich:datatable filtering, the source code of my page is like the site example:
<h:form id="form">
<rich:dataTable keepSaved="true" id="richTable" var="record" value="#{citiesBean}" rows="20">
<rich:column >
<f:facet name="header">
<h:commandLink action="#{bean.toggleSort}">
#{bean.sortOrders['cityTitle']}
<a4j:ajax render="richTable" />
<f:setPropertyActionListener target="#{bean.sortProperty}" value="#{'cityTitle'}" />
</h:commandLink>
<br />
<h:inputText value="#{citiesBean.filterValues['cityTitle']}">
<a4j:ajax render="richTable#body scroller" event="keyup" />
</h:inputText>
</f:facet>
<h:outputText value="#{record['cityTitle']}" />
</rich:column>
<rich:column >
<f:facet name="header">
<h:commandLink action="#{bean.toggleSort}">
#{bean.sortOrders['cityCode']}
<a4j:ajax render="richTable" />
<f:setPropertyActionListener target="#{bean.sortProperty}" value="#{'cityCode'}" />
</h:commandLink>
<br />
<h:inputText value="#{citiesBean.filterValues['cityCode']}">
<a4j:ajax render="richTable#body scroller" event="keyup" />
</h:inputText>
</f:facet>
<h:outputText value="#{record['cityCode']}" />
</rich:column>
<f:facet name="footer">
<rich:dataScroller id="scroller" />
</f:facet>
</rich:dataTable>
</h:form>
everything seems OK but it has some problems.
1- datascroller does not work without render attribute set to 'richTable' but it works on demo!!!
2-when i type something on filter input, the table does not get updated!, i have checked the request and response on firebug,
the response does not have a valid id, i mean it look like this:
<update id="form:richTable:tb"><tbody id="form:richTable:0:tb" ....
what is wrong with my codes?!
I am using, richfaces 4, Glassfish 3.1, Firefox 3.6
thanks in advance.

Answer 1

I think it was a kind of bug. Now it is fine with version 4.1 M1.
