Srs,
tenho o seguinte na minha view:
Meu controller:
@Post("/servidor")
public void salvar(final Servidor servidor) {
this.validator.validate(servidor);
Mas quando faço a submissão do formulário recebo um baita nullpointerexception.
Provavelmente por que a associação .pessoaFisica está nula quando o vraptor vai tentar inserir o conteúdo do campo nome dentro dela.
A exception:

Alguém sabe como resolver isso?
Preciso instanciar a pessoaFisica antes de mandar o servidor para a view?
Obrigado
