how selectitems and selectitem and converter

[alvaro tovar]

hello

maybe some one know this, i need have a list o objects merge with other
action selects, my idea is do sometinhg like

 <h:selectOneMenu value="#{reoffermanager.interestSelected}"
id="selectFilter"
                          style="font-family: Verdana, Arial, Helvetica,
sans-serif; font-size: 12px;"
valueChangeListener="#{reoffermanager.changeFilter}"
                          onchange="submit();">
                              <f:selectItems
value="#{reoffermanager.listFilter}"/>

                            <f:selectItem itemValue="-1" itemLabel="Filtros
disponibles" itemDisabled="true"/>
                            <f:selectItem itemValue="-2"
itemLabel="Filtro"/>
                            <f:selectItem itemValue="-7" itemLabel="Ocultar
descartados"/>
                            <f:selectItem itemValue="-8"
itemLabel="Funciones para filtros" itemDisabled="true"/>
                            <f:selectItem itemValue="-9" itemLabel="Nuevo
Filtro"/>

                          </h:selectOneMenu>

the list of selectitems i need to load some change in the
valueChangeListener="#{reoffermanager.changeFilter}" if i select some of
this no problem, but when i select other of the selectitem i have this error
j_id_id104:selectFilter: Error de Validación: Valor no es correcto.
j_id_id104:selectFilter: Error de Validación: Valor no es correcto. i 'am
using this converter mi idea is that when i select a selectitem, the
returned value was a new object whith the id of the itamvalue has, <0.

public class InterestConverter implements Converter{




    public final Object getAsObject(final FacesContext context,
            final UIComponent component, final String value) {
                ConstantManager constantsManager=(ConstantManager)
context.getApplication().getELResolver().getValue(
                        context.getELContext(),
                        null,"constantManager"
                        );
                if(value==null)
                {
                    return null;
                }

                Integer id=Integer.valueOf(value);
        Interest inter=constantsManager.getInterestById(id);
                if(inter!=null)
                {
                    return inter;
                }

                inter= new Interest();
                inter.setInterestedId(id);
                return inter;
    }

    public final String getAsString(final FacesContext context,
            final UIComponent component, final Object object) {
            if(object==null)
            {
                return null;
            }

            if(object instanceof Interest)
            {
                Interest constant=(Interest) object;
                return constant.getInterestedId().toString();
            }else if(object instanceof Integer)
            {
                Integer idAux=(Integer) object;

                return idAux.toString();
            }else if(object instanceof String)
            {
                return (String) object;
            }else
            {
                throw new IllegalArgumentException("object:
"+object.getClass().getName()+ " no es constante");
            }
    }


will be great if some one can help me
