can’t change my object from a datatable - JSF with Primefaces

Question

I am retrieving my object from the datatable more at the time I redirect the datatable to another page to make a change, it shows an error. More takes the Object ID, I made a convert more unsuccessfully.

my Converter

    package converter;

import javax.faces.component.UIComponent;
import javax.faces.context.FacesContext;
import javax.faces.convert.Converter;
import javax.faces.convert.FacesConverter;
import javax.inject.Inject;

import dao.FabricanteDAO;
import modelo.Fabricante;

@FacesConverter(forClass = Fabricante.class)
public class FabricanteConverter implements Converter {

    @Inject
    private FabricanteDAO dao;

    public Object getAsObject(FacesContext arg0, UIComponent arg1, String value) {
        Fabricante fabricante = null;

        if (value != null) {
            fabricante = this.dao.buscarPeloCodigo(new Long(value));
        }

        return fabricante;
    }

    public String getAsString(FacesContext arg0, UIComponent arg1, Object valor) {

        if (valor != null) {
            Fabricante fabricante = (Fabricante) valor;
            return fabricante.getCodigo() == null ? null : fabricante.getCodigo().toString();
        }
        return "";
    }

}

Change the notation @FacesConverter(forClass = Fabricante.class) by only:

@Named
public class FabricanteConverter implements Converter {

Package: javax.inject.Named;
