How to use a4j:support and rich:extendedDataTable with Seam

[sart]

Hello! I found that i can't make an ajax request. Here is the code:

xhtml:

<rich:extendedDataTable id="townPartList"
var="_townParts" selectionMode="single" width="365px"
height="190px" rendered="#{not empty fullAction.fullTownParts}"
value="#{fullAction.fullTownParts}">
    <f:facet name="header">Town Parts</f:facet>
         <a4j:support event="onRowClick" reRender="streetList" 
                      action="#{fullAction.retrieveStreets}">                                        
<f:param name="partId" value="#{_townParts.id}" />
</a4j:support>
<rich:column width="366px">
<h:outputText value="#{_townParts.description}" />
</rich:column>
</rich:extendedDataTable>

<rich:extendedDataTable id="streetList"
var="_street" selectionMode="single" width="365px" height="190px"
value="#{fullAction.fullStreetParts}">
<rich:column width="366px">
<h:outputText value="#{_street.description}" /> 
</rich:column>
</rich:extendedDataTable>

in Session Bean i want to start retrieveStreets(). But it's not doing nothing when i click the row in the first table.

Can anyone tell me what i do wrong. Thanks in advance.

There have been some issues with ExtendedDataTable with a4j.  Check the Richfaces forum and JIRA.

I'm doing stuff with rich:extendedDataTable components. I'm using the 3.3.0.GA version and have used it with both of toe latest GA versions of Seam. I'm using the onSelectionChange as my a4j:support event.

I don't know whether or not it matters, but I'm explicitly setting bypassUpdates to true. I'm not using a header facet. (That really shouldn't matter.)
