Phalcon BeforeSave не получает данные перед сохранением?

Прежде чем сохранить свою модель, я хотел бы проверить, $ CONT_CEDULA отвечает требованиям. Если нет, то не экономьте. Но при сохранении это как бы переменная $ CONT_CEDULA не имеет никаких данных Я хочу знать, хорошо ли я себя чувствую, или мне нужно другое мероприятие или функция. Так же echo не выводит данных

beforeSave метод

public function beforeSave() {

echo $this->$CONT_CEDULA;
switch (strlen($this->$CONT_CEDULA)) {
case 10:
return validarCI($this->$CONT_CEDULA);
break;
case 13:
return validarRUC($this->$CONT_CEDULA);
break;
default:
echo "Numero de caracteres invalidos"  ;
return FALSE;
}
