JSF - Custom validator executed, no problems found, but execution flow does not arrive in Managed Bean

Question

I created a Custom Validator, referenced it in a <h:inputText>, Validator runs, no exception is raised, but the execution flow does not arrive in Managed Bean.

Where I must be going wrong?

<h:inputText id="cpf" size="18" maxlength="14" rendered="true" value="#{managedBean.usuario.CPF}">
  <c:validator validatorId="cpfValidator" />
</h:inputText>

package br.web.jsf.validators;

import javax.faces.application.FacesMessage;
import javax.faces.component.UIComponent;
import javax.faces.context.FacesContext;
import javax.faces.validator.FacesValidator;
import javax.faces.validator.Validator;
import javax.faces.validator.ValidatorException;

import br.util.BibliotecaMetodos;

@FacesValidator("cpfValidator")
public class CPFValidator implements Validator {
	
	@Override
	public void validate(FacesContext pFacesContext, UIComponent pUiComponent, Object pObject) throws ValidatorException {
		String cpf = (String) pObject;
		
		if ( !BibliotecaMetodos.isCPFvalido(cpf) ) {
			FacesMessage mensagem = new FacesMessage("O CPF é Nulo ou Inválido.");
			mensagem.setSeverity(FacesMessage.SEVERITY_ERROR);
			
			throw new ValidatorException(mensagem);
		}
	}
	
}
