I am trying to create a form using BeanFieldGroup, but every time I do I get this exception commit:

This is part of the code of the form and do not see why this exception:

Label section = new Label(Constante.getString(Titulos.DIRECCION));
        section.addStyleName(ValoTheme.LABEL_H3);
        section.addStyleName(ValoTheme.LABEL_COLORED);

            }
        });
        form.addComponent(paisBox);

            }
        });
        form.addComponent(departamentoBox);

Maybe geteMail() and seteMail() methods names need to change to getEMail() and setEMail() ?

Yes. I had already noticed but the problem is not in this field. the problem is in the address field as not recognizing me this editFGroup.bind(direccionArea, "direccion.direccion");. field nested in class. and do not know why that happens is supposed to detect without problem.
