selectonemenu not selecting the backbean value

[Juan Pablo Ram�rez]

I have this problem, my object instructor is getting the correct activity value from the h:selectonemenu when is inserted to the database, but when I restart the server and consult the instructor data it renders the default value, ignoring the 'real' value. I even put an ouputText element to see the expected value and it is correct, but no with the selectonemenu.

this is my instructor

public class Instructores {
private Integer id;
private Ctdc ctdc;
private Actividades actividad;
 
private String numero;
private String nombre;
public Actividades getActividad() {
return actividad;
}
public void setActividad(Actividades actividad) {
this.actividad = actividad;
}
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getNombre() {
return nombre;
}
public void setNombre(String nombre) {
this.nombre = nombre;
}
public String getNumero() {
return numero;
}
public void setNumero(String numero) {
this.numero = numero;
}
}

This is where I fill the actividades list

private void fillListSelectActividades() {
Session session = HibernateFactory.currentSession();
Transaction txn = session.beginTransaction();
List l = (List) session.createQuery("from Actividades").list();
txn.commit();
HibernateFactory.closeSession();
 
Iterator i = l.iterator();
while (i.hasNext()) {
Actividades act = (Actividades) i.next();
listSelectActividades.add(new SelectItem(act, act.getNombre()));
mapActividades.put(String.valueOf(act.getId()), act);  // <-- paralel map with objects for the converter
}
}

This is my custom converter for this class

public class ActividadesConverter implements Converter {
 
protected Logger log = Logger.getLogger("ActividadesConverter");
 
public ActividadesConverter() {
}
 
public String getAsString(FacesContext facesContext,
UIComponent uiComponent, Object obj) {
return String.valueOf( ((Actividades) obj).getId() );
}
 

public Object getAsObject(FacesContext facesContext,
UIComponent uIComponent, String str) throws ConverterException {
FacesContext fc = FacesContext.getCurrentInstance();
    VariableResolver vr = fc.getApplication().getVariableResolver();
    Object temp = vr.resolveVariable(fc, "instructoresmodel");
    // instructoresmodel is the managedbean holding the list and the map

HashMap map = ((InstructoresModel) temp).getMapActividades();
Actividades act = (Actividades) map.get(str);
log.severe("********Got: " + act.getNombre() + " as: " + act.hashCode());
 
if (act == null) {
FacesMessage message = new FacesMessage(
FacesMessage.SEVERITY_ERROR, "Unknown Actividad",
"The Actividades value chosen was not recognized");
throw new ConverterException(message);
}
 
return act;
}

}

The jsp fragment

...
<%-- ***  SELECTONEMENU ACTIVIDADES ***  --%>
<h:outputText value="Actividad"></h:outputText>
<h:panelGroup>
<h:outputText value="#{instructoresmodel.currentInstructor.actividad}"></h:outputText>
<h:selectOneMenu value="#{instructoresmodel.currentInstructor.actividad}" converter="ActividadesConverter">
<f:selectItems value="#{instructoresmodel.listSelectActividades}" />
</h:selectOneMenu>
<h:messages/>
</h:panelGroup>
 
...

Notice the <hutputText, it does print the correct value but the <h:selectOneMenu doesn't.

It's a strange behavior...

Please comment.
