    DataTable as children in a rich:tree

    Cavaignac sébastien Newbie

      Hi,

      I would to display DataTable components as children in a richfaces tree instead of a simple string.

      Here is my code for the moment.

      But instead of displaying the dataTable, it displays the reference like "org.richfaces.component.html.HtmlDataTable@92a094"

      My JSP:

      <rich:tree style="width:300px" nodeSelectListener="#{SimpleTreeBean.processSelection}"

      reRender="selectedNode" ajaxSubmitSelection="true" switchType="client" icon="../../commun/Images/24.gif"
      iconCollapsed="../../commun/Images/iPlus.gif"
      iconExpanded="../../commun/Images/iMoins.gif"

      value="#{SimpleTreeBean.treeNode}" var="item">

      <rich:treeNode type="simpleNode" >
      <rich:dataTable value="#{item.hdt}" />
      </rich:treeNode>


      </rich:tree>


      The class describing the tree:
