I am using richfaces 3.3.0.CR2
when I try any action for example click on sort icon, i expect to the rows be sorted ASC or DESC.
but only i got the load icon (like in progress) and then nothing happend.

this any action i do like column hide/show etc.

<h:form>
 <rich:extendedDataTable value="#{adminUserService.adminUsers}" var="user"
 columnClasses="usermanager_id_col,usermanager_name_col" sortMode="single" width="800px" height="300">
 <rich:column sortBy="#{user.id}" width="100" sortable="true">
 <f:facet name="header">
 <h:outputText value="Id"/>
 </f:facet>
 <h:outputText value="#{user.id}"/>
 </rich:column>
 <rich:column sortBy="#{user.username}" width="700" sortable="true" >
 <f:facet name="header">
 <h:outputText value="Name"/>
 </f:facet>
 <h:outputText value="#{user.username}"/>
 </rich:column>
 </rich:extendedDataTable>
 </h:form>
