Bom dia!

Galera eu estou precisando de umas dicas. Estou fazendo uma tela de cadastro porem algumas informações como estados, tipo de endereço prefiro colocar no Dai começou as dores de cabeça.

segue abaixo o meu codigo.

DAO 
public List<Estado> getEstado() {
		sessao = HibernateUtil.getSessionFactory().openSession();
		Query query = sessao.createQuery("select uf from Estado");
		return query.list();
	}
Controller 
public List<SelectItem> getItem() {
		SelectItem selectItem = new SelectItem();
		List<Estado> list = new ArrayList<Estado>();

		list = estadoDAO.getEstado();

		for (Estado e : list) {
			selectItem.setValue(e.getUf());
			selectItem.setLabel(e.getUf());
			item.add(selectItem);
		}
		return item;
	}

.xhtml

<h:selectOneMenu id="txt_tipo" value="#{item.endereco.tipo}">
								<f:selectItem itemLabel="Selecione" itemValue="Selecione" />
								<f:selectItems value="#{uf.item}" />//lembrando que esse "uf" é outro controller , diferente do controller item
							</h:selectOneMenu>

que resulta no erro 500
