    NullPointerException when sorting a dataTable

    Some Kid Newbie

      Hi All,
      I have a datatable that I need to be able to sort by some of it's columns.
      It all worked fine until I added the attributes in bold to the dataTable element. This is to ensure that when first rendered the table is sorted by this column.


      <rich:dataTable value="#{myBean.myData}" sortMode="single" sortPriority="#{_b.myProp}"
       var="_b"
       rendered="#{myBean.myData}"
       id="myDataTable">
      
       <rich:column sortBy="#{_b.myProp}" id="myProp" sortOrder="DESCENDING" sortable="true">
       <f:facet name="header">Prop</f:facet>
       <h:outputText value="#{_b.myProp}" />
       </rich:column>
      
       <!-- OTHER COLUMNS -->
      
      </rich:dataTable>


      The problem is that when II now click on that column's header I get the following exception:

      14:16:41,994 ERROR [lifecycle] JSF1054: (Phase ID: APPLY_REQUEST_VALUES 2, View ID: /myPage.xhtml) Exception thrown during phase execution: javax.faces.event.PhaseEvent[source=com.sun.faces.lifecycle.LifecycleImpl@1ba52c]
