estou tentando inserir um novo objeto no meu formulário. Ao tentar entrar nesta pagina, aparece um erro..
OBS: Possuo 2 páginas cadastrar e consultar só que consigo recuperar meu objeto na pagina consultar e atualizar, quando vou diretamente para inserir, ele apresenta esse erro, creio eu que é alguma coisa haver com converter
Meu converter
package com.irmaosuspension.controleservico.converter;
import javax.faces.component.UIComponent;
import javax.faces.context.FacesContext;
import javax.faces.convert.Converter;
import javax.faces.convert.FacesConverter;
import com.irmaosuspension.controleservico.cdi.CDIServiceLocator;
import com.irmaosuspension.controleservico.dao.FabricanteDAO;
import com.irmaosuspension.controleservico.modelo.Fabricante;
@FacesConverter(forClass = Fabricante.class)
public class FabricanteConverter implements Converter {
private FabricanteDAO fabricanteDAO;
public FabricanteConverter() {
this.fabricanteDAO = CDIServiceLocator.getBean(FabricanteDAO.class);
}
public Object getAsObject(FacesContext context, UIComponent component, String value) {
Fabricante retorno = null;
if (value != null) {
retorno = this.fabricanteDAO.buscarPeloCodigo(new Long(value));
}
return retorno;
}
public String getAsString(FacesContext context, UIComponent component, Object value) {
if (value != null) {
Long codigo = ((Fabricante) value).getCodigo();
String retorno = (codigo == null ? null : codigo.toString());
return retorno;
}
return "";
}
