Problema com validadores JSF

Olá galera,
Estou tentando reproduzir um código de uma video aula, e estou tendo uns resultados estranhos nos validadores JSF.
Para que alguém possa me ajudar, estarei colocando o código completo, o qual não é muito grande. E o erro está na imagem em anexo. Reparem as msgs de validação retornadas.
