I'm attempting to do a simple list and detail display model with the richfaces data table.

From what I can tell, I should use a <a4j:support.../> tag within the <rich:dataTable .../> tag to trigger the selection on the onRowClick event.

However, my action handler never gets called, and I can't work out why.

I have a page of the following form:

<a4j:form id="contactForm" ajaxSubmit="true">
 <rich:panel>
 <rich:dataTable
 id="otherPartyList"
 rows="10"
 width="100%"
 var="party"
 rowKeyVar="row"
 value="#{contact.interestedParties}"
 binding="#{contact.interestedPartiesTable}">
 <a4j:support event="onRowClick" action="#{contact.selectRow}" reRender="selectedOtherPartyFragment"/>
 <rich:column sortable="false">
 <f:facet name="header">
 <f:verbatim>Row</f:verbatim>
 </f:facet>
 <h:outputText value="#{row}" />
 </rich:column>
 <rich:column sortBy="#{party.title}">
 <f:facet name="header">
 <f:verbatim>Title</f:verbatim>
 </f:facet>
 <h:outputText value="#{party.title}" />
 </rich:column>
 <rich:column sortBy="#{party.name}">
 <f:facet name="header">
 <f:verbatim>Name</f:verbatim>
 </f:facet>
 <h:outputText value="#{party.name}" />
 </rich:column>
 </rich:dataTable>

 <a4j:outputPanel id="selectedOtherPartyFragment">
 <f:subview id="detail" rendered="#{contact.selectedParty != null}">
 <rich:spacer height="10px"/>
 <h:outputText value="#{party.title}" />
 <h:outputText value="#{party.name}" />
 </f:subview>
 </a4j:outputPanel>
 </rich:panel>
</a4j:form>

and my backing bean (contact) is of this form:

package com.workcover.clw.noc.web.managedBean;

import java.io.Serializable;
import java.util.ArrayList;
import java.util.List;

import org.richfaces.component.html.HtmlDataTable;

import com.workcover.clw.noc.domain.InterestedPartyDetails;

public class ContactTab implements Serializable {
 /** Version ID */
 private static final long serialVersionUID = 4260048709217435243L;
 private List<InterestedPartyDetails> interestedParties;
 private InterestedPartyDetails selectedRow;
 private transient HtmlDataTable interestedPartiesTable;

 public ContactTab() {
 ... set up some test InterestedPartyDetails objects in interestedParties ...
 }

 public List<InterestedPartyDetails> getInterestedParties() {
 return interestedParties;
 }

 public HtmlDataTable getInterestedPartiesTable() {
 return interestedPartiesTable;
 }

 public void setInterestedPartiesTable(HtmlDataTable interestedPartiesTable) {
 this.interestedPartiesTable = interestedPartiesTable;
 }

 public String selectRow() {
 Object obj = getInterestedPartiesTable().getRowData();
 selectedRow = (InterestedPartyDetails) obj;
 return null;
 }

 public InterestedPartyDetails getSelectedParty() {
 return selectedRow;
 }
}

Does anyone have some ideas as to what I am doing wrong? I can't imagine that such a simple interaction can be difficult, but I'm stumped.
