Hey all,
I'm using a rich:dataTable within a rich:tabPanel and am getting the following error:

javax.servlet.ServletException: duplicate Id for a component j_id_jsp_917984629_12:j_id_jsp_917984629_14
 at javax.faces.webapp.FacesServlet.service(FacesServlet.java:256)

I am using the following markup:

<!-- Main Tabs -->
<rich:tabPanel switchType="server" headerClass="tab-header"
 contentClass="tab-content">
 <rich:tab label="Home">
 <rich:dataTable value="#{testBean.results}" var="row"
 style="text-align:left" rows="10">
 <rich:columns value="#{testBean.columnHeaders}" var="columnHeader" >
 <f:facet name="header">
 <h:outputText value="#{columnHeader}" />
 </f:facet>
 <h:outputText value="#{row[columnHeader]}" />
 </rich:columns>
 <f:facet name="footer">
 </f:facet>
 </rich:dataTable>
 </rich:tab>
 <rich:tab label="Program View">
 </rich:tab>
</rich:tabPanel>

... and the following TestBean:

public class TestBean {

 private List<Map<String,String>> results;
 private List<String> columnHeaders;

 public TestBean()
 {
 columnHeaders = new ArrayList<String>();
 columnHeaders.add("col1");
 columnHeaders.add("col2");
 columnHeaders.add("col3");
 results = new ArrayList<Map<String,String>>();
 Map<String, String> result1 = new HashMap<String, String>();
 result1.put("col1", "col1row1");
 result1.put("col2", "col2row1");
 result1.put("col3", "col3row1");
 results.add(result1);
 Map<String, String> result2 = new HashMap<String, String>();
 result2.put("col1", "col1row2");
 result2.put("col2", "col2row2");
 result2.put("col3", "col3row2");
 results.add(result2);
 Map<String, String> result3 = new HashMap<String, String>();
 result3.put("col1", "col1row3");
 result3.put("col2", "col2row3");
 result3.put("col3", "col3row3");
 results.add(result3);
 }

 public List<Map<String, String>> getResults() {
 return results;
 }
 public List<String> getColumnHeaders() {
 return columnHeaders;
 }
}

If I use Tomahawk's dataTable, it works fine. Any ideas why it's not working with RichFaces?
Thanks for any insight!
