I was trying to sort data table rows by a specific value... then I found property 'sortable' in rich:Column component but it didn't work. Here is my code:

<rich:dataTable border="1"
 value="#{userNormalBackingBean.userNormalDataManager.allUsers}"
 var="table" binding="#{userNormalBackingBean.table}" id="userTable"
 rows="5">

 <f:facet name="header">
 <h:outputText id="tableTitle" value="Normal Users" />
 </f:facet>

 <rich:column id="column1" sortable="true">
 <f:facet name="header">
 <h:outputText id="header1" value="NAME" />
 </f:facet>
 <h:outputText id="value1" value="#{table.name}" />
 </rich:column>

 <rich:column id="column2" sortable="true">
 <f:facet name="header">
 <h:outputText id="header2" value="LAST NAME" />
 </f:facet>
 <h:outputText id="value2" value="#{table.lastName}" />
 </rich:column>
</rich:dataTable>

I need to sort table by clicking the column header .... It was supposed that rich have implemented that with sortable property....

Thanks a lot!
