    <af:table var="test1" value="#{collectionDnD.sourceValues}" id="table" 
          summary="generic drag source"
                     rowSelection="single">
      <af:column headerText="Product">
        <af:outputText value="#{test1.product}"/>
      </af:column>
      <af:column headerText="Cost">
        <af:outputText value="#{test1.cost}"/>
      </af:column>
      <af:dragSource actions="COPY" discriminant="DnDDemoModel"/>
    </af:table>

    <af:table var="test2" value="#{collectionDnD.targetValues}" id="table2"
              summary="collection drag source"
              rowSelection="single">
      <af:column headerText="Product">
