Hi ... First, sorry for my english... I'm brazilian
I have a class Acao whith a subclass GeracaoPergunta (In the future will be more) and when I try to get a Acao from "ControleAcao" (Acao one of ControleAcao pks) I get a error casting it to GeracaoPergunta.
When I load Acao using session.load... the type retrieved is the subclass type ... Ok
When I get Acao from "ControleAcao" it's impossible to cast it to the subclass...
Acao is a abstract class.
Example that works:
Code:
public void testInheritence() {
try {
Session s = Ambiente.getInstance().getSession();
Object object = s.load(Acao.class, 3);
assertNotNull(object);
System.out.println("Pro Christian acreditar:" + object.getClass().toString());
if (!(object instanceof GeracaoPergunta))
{
fail("Classe deveria ser do tipo GeracaoPergunta");
}
} catch (Exception err) {
err.printStackTrace();
}
}
Example that not works:
Code:
public void testAcoes() {
Session s = Ambiente.getInstance().getSession();
Pergunta p = (Pergunta) s.load(Pergunta.class, 4);
Objeto o = (Objeto) s.load(Objeto.class, 8);
List controles = ControleAcao.getDAO().getControleAcaoList(p, o);
for (Object controle : controles) {
Acao acao = controle.getAcao();
if (!(acao instanceof GeracaoPergunta)) {
fail("Must be GeracaoPergunta... but is: " + acao.getClass().toString());
}
}
}
I'm going crazy with that !! :/
Any help will be apreciated, thanks
