    null entityManager in Converter

    jmchiaradia Jun 8, 2009 7:17 PM

      Hello,


      I have a converter that get an Entity Object from a name (nombre).


      @Name("perfilConverter")
@Converter(forClass=Perfil.class)
@BypassInterceptors
public class PerfilConverter implements javax.faces.convert.Converter{

     @In EntityManager entityManager;
     
     public Object getAsObject(FacesContext context, UIComponent component, String nombre) {
          Query query = entityManager.createNamedQuery("perfil.getFromNombre");
          query.setParameter("nombre", nombre);
          return query.getSingleResult();
     }

     public String getAsString(FacesContext arg0, UIComponent arg1, Object perfil) {
          return ((Perfil)perfil).getNombre();
     }

}



      When I run this example, I have this error:


      GRAVE: JSF1054: (Phase ID: PROCESS_VALIDATIONS 3, View ID: /admin.UsuarioEdit.xhtml) Exception thrown during phase execution: javax.faces.event.PhaseEvent[source=com.sun.faces.lifecycle.LifecycleImpl@1292ff8]
