    Rerendering a column of the containing datagrid

    Cle' Diggins Newbie

      I have a datagrid with 5 columns. In one of these columns there is a dropdown of objects that can add or remove a column depending on what is selected. As of now, it seems this does not work. I can have the dropdown render various numbers of columns in other datagrids on the page, but so far have been unable to get it to add or remove a column from the datagrid that it is contained within. Am I missing something, or is this not supported by richFaces?

      <rich:dataTable
       rowClasses="seamDisplayTableRowOne,seamDisplayTableRowTwo"
       rules="cols" value="dailyUse">
       <h:column>
       <f:facet name="header">Date</f:facet>
       <h:inputText value="#{dailyUse.siActivityDateString}" />
       </h:column>
       <h:column>
       <f:facet name="header">Operator</f:facet>
       <h:selectOneMenu value="#{dailyUse.siEmployee}"
       converter="#{employeeBean.employeeConverter}">
       <s:selectItems
       value="#{employeeBean.loadEmployeesForCurrentDepartment}"
       var="employee" label="#{employee.siEmployeeName}" />
       </h:selectOneMenu>
       </h:column>
       <h:column>
       <f:facet name="header">Equipment</f:facet>
       <h:selectOneMenu value="#{dailyUse.siEquipment}"
       converter="#{equipmentBean.equipmentConverter}">
       <s:selectItems
       value="#{equipmentBean.loadEquipmentForCurrentDepartment}"
       var="equip" label="#{equip.psTagNumber}" noSelectionLabel="Select Equipment" />
       <a:support event="onchange" reRender="milesHoursGrid,PTOColumn" action="#{dailyUseBean.clearMilesHoursList}" />
       </h:selectOneMenu>
       </h:column>
       <h:column>
       <f:facet name="header">Billing Dept</f:facet>
       <h:outputText value="#{user.currentDepartment.psDeptID}" />
       </h:column>
       <s:span id="PTOColumn">
       <h:column>
       <f:facet name="header">Power Take Off(lbs)</f:facet>
       <h:inputText rendered="#{dailyUse.siEquipment.siPowerTakeOff}" value="#{dailyUse.siPowerTakeOff}" />
       </h:column>
       </s:span>
       </rich:dataTable>
      


      In the above example, I am trying to get the 'Power Take Off(lbs)' column to render depending on what is selected in the Equipment dropdown.

      If I put the 'rendered' property just around the inputText for powertakoff, that input text does reRender and appear and disappear as it should, but I am left with an empty column. My objective is to get that column to appear is disappear as it needs to.

      Thanks.
