Hello staff'm trying to make a layout with datascroller together with the hibernate but not yet received success, see the code:

 public DataModel Paginacao(){
 System.out.println("chamou o metodo..................:");
 HtmlDatascroller htmlDatascroller = (HtmlDatascroller) FacesContext.getCurrentInstance().
 getViewRoot().findComponent("scrollnum");
 System.out.println("getIndexPage..................:"+getIndexPage()+1);
 if ((getIndexPage()+1)== getMaxPages()) {
 System.out.println("getIndexPage..................:"+getIndexPage()+1);
 System.out.println("MaxPage..................:"+getMaxPages());
 setMaxPages(maxPages + 5);
 System.out.println("MaxPages..................:"+getMaxPages());

 IDaoNumeracao idao =new DaoNumeracao();
 model =(DataModel) new ListDataModel(idao.ListarTodosPaginados( ( getIndexPage()+1 )*10) );
 setModel(model);

 return model;

 }
 setMaxPages(5);
 return null;
 }

e o metodo no dao

@SuppressWarnings("unchecked")
 public List<Numeracao> ListarTodosPaginados(Integer index) {
 session = HibernateUtil.getInstance();
 try{
 List<Numeracao> list =session.createQuery("from Numeracao n order by n.numeracaoid")
 .setFirstResult(index).setMaxResults(50).list();
 return list;
 } finally {
 session.close();
 }

 }

o scroller

 <a4j:outputPanel ajaxRendered="true">
 <rich:datascroller id="scrollnum" align="center" for="tbnumeracao"
 maxPages="#{numeracao.maxPages}" style=" width : 739px;" ajaxSingle="true"
 page="#{numeracao.indexPage}" action="#{numeracao.Paginacao}"/>
 </a4j:outputPanel>

What happens is that once the last page of the scroll he does select in the bank but does not update the dataSroller, someone could help me?
you, hugging.
