[size=18]Bom Dia!!!
[b]Estou com um form onde disparo um get no jQuery para o controller que usa o vRaptor 3 e preciso que retorne um jSon com a mensagem após executar um sql no jdbc. Isso sempre funcionou … pelo menos em todos os métodos dos controllers que desenvolvo.
Ocorre que há uns 20 dias ocorre algo estranho, após executar o método no controller, como a mensagem …:
[/b]
<a class="mention" href="/u/get">@Get</a>
<a class="mention" href="/u/path">@Path</a>("/avaliacao/gravarAvaliacaoJson.json")
public void gravarAvaliacaoJson(Avaliacao avaliacao) {
if((avaliacao.getCidadao().getId()!=null)&&(avaliacao.getTurma().getId()!=null)
&&((avaliacao.getPeriodoAvaliativo1().getStatusAvaliativo().getId()!=null)
||(avaliacao.getPeriodoAvaliativo2().getStatusAvaliativo().getId()!=null)
||(avaliacao.getPeriodoAvaliativo3().getStatusAvaliativo().getId()!=null)
||(avaliacao.getPeriodoAvaliativo4().getStatusAvaliativo().getId()!=null)
||(avaliacao.getPeriodoAvaliativo5().getStatusAvaliativo().getId()!=null))){
avaliacao.setUsuario(this.usuarioWeb.getUsuario());
avaliacao = new AvaliacaoDao().gravarAvaliacao(avaliacao);
}
// até aqui o método ocorre tudo normal, grava no BD, retorna a mensagem … porém doravante … não funciona …
this.result.use(Results.json()).withoutRoot().from(avaliacao).include(“msg”).serialize();
/*
a classe Avaliacao contem o objeto (classe) Mensagem que contém o objeto (texto) descricao
*/
}
… no console do eclipse retorna o erro …:

If you didn’t add any validation error, it is possible that a conversion error had happened.
