Getting stack trace when using groupBy attribute in

[Paul Spencer <pa...@apache.org>]

(MyFaces 1.1.3, Tomahawk 1.1.3)

I am receiving a stack trace when coordinating the groupBy column with the
sorting column.  The variable created by sortColumnVar is used to in
<t:column>'s groupBy attribute.  When I click on a column header I receive a stack trace.

I have verified the variable "sortedColumn" is correctly set.

**
* From the JSP
**
   <t:dataTable value="#{list.rows}" var="row"
                sortedColumnVar="sortedColumn">
     <t:column sortable="true" sortPropertyName="col_1"
               groupBy="#{sortedColumn}">
       <f:facet name="header">
         <h:outputLabel value="Col 1" />
       </f:facet>
       <h:outputText value="#{row.col_1}" />
     </t:column>
   </t:dataTable>

Do I need to report this as an issue?
