Retrieving data from Hibernate

[Jesus Schneider]

Hi!
I'm programming a JSF+hibernate web application wit Netbeans 7.2.
I'm trying to populate a selectOneMenu with data from the database with this code:

private ArrayList<SelectItem> generaTiposUsu() {  

   ArrayList<SelectItem> todos=new ArrayList<SelectItem>();

   Session sesion=HibernateUtil.getSessionFactory().openSession(); 
   try {       
        sesion.beginTransaction();
        Query query = sesion.createQuery("select tip.tipCod,tip.tipDesing from Tipos tip where tip.tipCod<>'ADM' ");
        List resultados = query.list();
        if (!resultados.isEmpty()){            
            for(Object o : resultados) {
                 todos.add(new SelectItem(o) );     <=== PROBLEM HERE!!!         
            };
        };            
        sesion.getTransaction().commit();
        sesion.close();                                  
    }
     catch (HibernateException he) {
        System.out.println("ERROR.");
        };
     return todos;
}

The code above works fine (HQL and so on...) but there is a problem. The selectOneMenu gets populated with what seems SelectItems with the Object.toString(), not the CODE and DESCRIPTION.
I have debugged the data and it seems that the objects returned by the LIST are composed of 2 String (CODE, DESCRIPTION).
How can I do to transform the Object returned by the query.LIST into a SelectItem???

Thanks in advance!!

Ok, it's easier after you take a closer look at the data.

Session sesion=HibernateUtil.getSessionFactory().openSession(); 
   try {       
        sesion.beginTransaction();
        Query query = sesion.createQuery("select tip.tipCod,tip.tipDesing from Tipos tip where tip.tipCod<>'ADM' ");
        List resultados = query.list();
        if (!resultados.isEmpty()){                              
            for(Object o : resultados) {  
                Object[] arraytemp = (Object[])o; 
                todos.add(new SelectItem((String)arraytemporal[0],(String)arraytemporal[1]));                              
            };
        };            
        sesion.getTransaction().commit();
        sesion.close();                                  
    }
     catch (HibernateException he) {
        System.out.println("ERROR.");
        };
     return todos;
