Pessoal, ja pesquisei no forum, e existem um bocado de erros com conversão de data mas não encontrei nenhum que seja semelhante ao meu.
O erro deve ser bem simples pra que ja tem pratica com o JSF… mas pra quem esta começando como eu esta complicado.
1º Informação: meu crud ja esta todo funcionando, só da erro quando tento exibir um campo Date ou inserir um dado Date no banco
2º Informação: Ja tentei com trocar o Pessoa.nascimento para Util.Date e Calendar, porem ambos não funcionaram.
3º Informação: O campo Pessoa.nascimento é do tipo DATE, meu banco é mysql.
Alguem ai pode me ajudar?
Seguem meus codigos:
