ldanielts:
Cara,
Está com a cara de um problema que eu já tive.
Mas, pra saber se é mesmo, gostaria que você mandasse o stack trace inteiro.
Veja se na trace tem alguma ArrayIndexOutOfBounds.
Um abraço.
como pego o stacktrace completo? esse ai eh o que eh retornado na pagina, quando o erro acontece.
vou colocar aqui as classes queestou usando para vcs verem, mas acho que o faces-config.xml e o resto tá tudo okei.
Imagens.java (classe que contem o array de byte e o integer id)
package dominio;
public class Imagens {
private byte[] documento;
private Integer id;

}
public void setId(Integer value) {
this.id = value;
