Provalvelmente vc tem q colocar o dataTable dentro de um <h:form> porque o datascroller faz requests

Rodrigo_Oliveira · Agosto 4, 2010, 11:46pm

vc precisa colocar o componente datascroller abaixo do fim da tag do componente dataTable e o h:form.

         </rich:dataTable>  
         <rich:spacer height="10" />
         <rich:datascroller  id="scroller" for="alunos" maxPages="10" />
     </h:form>
 </f:view>
