Codigo:

@Post
	public void adiciona(T obj) {
		this.objeto = obj;
		this.validator.addAll(Hibernate.validate(obj));
		this.validator.onErrorUse(Results.logic()).redirectTo(getClass()).formulario();
		//.forwardTo(getClass()).formulario();
		this.daoGenerico.getDao().adiciona(obj);
		this.result.use(Results.logic()).redirectTo(getClass()).formulario();		
	}

Lucas Cavalcanti:
crie a classe MyOutjector que está no final desse tópico por enquanto:

http://www.guj.com.br/posts/list/148774.java#807960

vai resolver esse problema… vou investigar esse bug…

vc poderia me mandar quais parâmetros foram mandados pra requisição qdo deu esse erro por favor?

funcionou com MyOutject estou passando um objeto para gravacao com os seguintes campos

public class CadTipoDocumento() {
	@NotEmpty
	@Length(min=5, max=40)
	@Column(length=40, columnDefinition="varchar(40)", nullable=false)
        private String descricao;
	@NotEmpty
	@Length(min=5, max=40)
	@Column(length=40, columnDefinition="varchar(40)", nullable=false)
        private String especie;
        /* get set */
}

Para provocar este erro digitei no campo descricao somente 1 caracter para fazer validacao @Length estou usando GenericController.

Obrigado !!!
