vai as aplicações

jsp

	<f:view>
		
		 <h:selectOneMenu value="#{Estado.id}">  
      		  <f:selectItems value="#{Estado.todosEstados}" />  
   		 </h:selectOneMenu>  
	</f:view>

classe estado(nao acho certo esse codigo fikar no meu modelo)

  public class Estado {

	@GeneratedValue
	@Id
	private long id;
	
	private String nome;

	public List<SelectItem> getTodosEstados() {  
		
		Session s = HibernateUtil.getSession();
		EstadoDAO estadoDAO = new EstadoDAO(s);
        List<Estado> listaEstados = estadoDAO.buscaLista();
        List<SelectItem> listaSelect = new ArrayList<SelectItem>();  
         
        for(Estado e : listaEstados){  
            listaSelect.add(new SelectItem(e.getId(), e.getNome()));  
        }  
           
        return listaSelect;  
   }

o meu dao eh generico

	public List<T> buscaLista() {
		session.beginTransaction().begin();
		logger.info("ListandoTodosGenerico " + persistentClass );
		List<T> lista =  session.createCriteria(persistentClass).list();
		session.beginTransaction().commit();
		return lista;
	}

Eu não consigo ver como usar JSF e vraptor. São dois frameworks que fazem a mesma coisa de formas diferentes. Você não consegue trabalhar com o container do JSF em vraptor, nem o JSF consegue usar o contexto do vraptor.

criei outro projeto…sem o vraptor agora…

e o erro continua…

Acho melhor você postar essa dúvida lá no fórum de JSF, ou então mover para lá, não sei se tem como. Eu particularmente conheço JSF mas não gosto e por isso não uso no dia a dia, então não consigo te ajudar. Se fosse vraptor eu conseguiria.

Abraços
