Richfaces 4.5.0 - converter in rich:select

[laurent.hever]

Hi,

I found the following "problem".

I have a rich:select with some values an a "default" value which is null.

When I select a "valid" value and then want to go back to the "null" value, the converter isn't invoked.

However when I replace the rich:select component with a h:selectOneMenu, everything is working as excpected.

here my code (this one is working)

<h:selectOneMenu defaultLabel="Veuillez sélectionner"
                                 id="slcAnnee"
                                 style="width: 100px;"
                                 converter="#{saisonConverter}"
                                 value="#{sessionDataBean.currentSelectedSaison}" >
     <f:selectItem itemLabel="---" itemValue="#{null}" noSelectionOption="true"/>
     <f:selectItems value="#{saisonFacade.all}"
                    var="saison"
                    itemLabel="#{saison.libelle}"
                    itemValue="#{saison}"/>
     <f:ajax event="change" render="tblIntervention saison" execute="@this"/>"
</h:selectOneMenu>

Here my Abstract Vonverter class which i am extending

public abstract class AbstractDbObjectConverter implements Converter {
    @PersistenceContext
    private EntityManager em;


    public abstract Class getEntityClass();


    public Object getAsObject(FacesContext facesContext, UIComponent component, String id) {
        try {
            return em.find(getEntityClass(), Long.parseLong(id));
        } catch (IllegalArgumentException ignored) {
        }
        return null;
    }


    public String getAsString(FacesContext facesContext, UIComponent component, Object obj) {
        if (obj == null) return null;
        if (obj instanceof String && ((String) obj).trim().length() == 0) return null;
        if (obj instanceof DBObject) {
            return ((DBObject) obj).getId().toString();
        }
        return null;
    }
}

here is the actual converter

@Model
public class SaisonConverter extends AbstractDbObjectConverter {
    @Inject
    private Logger log;


    public Class getEntityClass() {
        return Saison.class;
    }


    @PersistenceContext
    private EntityManager em;


    @Override
    public Object getAsObject(FacesContext facesContext, UIComponent component, String id) {
        log.info("getAsObject...");
        log.info("getAsObject.id: >"+id+"<");


        try {
            return em.find(getEntityClass(), Long.parseLong(id));
        } catch (NumberFormatException nfe) {
            log.info("NumberFormatException: " + nfe);
        }   catch (NoResultException nre) {
            log.info("NoResultException: " + nre);
        }
        return null;
    }
}

Thanks for any suggestion,

Laurent
