Boa noite!
Estou ha um tempo aqui tentando ver porque não está deletando um registro e gostaria de uma ajudinha ai pra desempacar nisso
Quando clico pra deletar ele passa por tudo e até mostra mensagem que foi deletado, mas no debug ele não pega o registro selecionado… fica tudo em null…mas nao acho o erro e para editar e inserir está tudo ok… quem puder me ajudar ai por favor… valeu
Estou usando hibernate, jsf, primefaces e spring security
ChangesDaoImpl
public class ChangesDaoImpl implements ChangesDao {
@Override
public void inserir(Changes changes) {
Session session = HibernateUtil.getSessionFactory().openSession();
try {
session.beginTransaction();
session.save(changes);
session.beginTransaction().commit();
} catch (Exception e){
System.out.println("Erro ao inserir: "+e.getMessage());
session.beginTransaction().rollback();
}
}
@Override
public void excluir(Changes changes) {
Session session = HibernateUtil.getSessionFactory().openSession();
try {
session.beginTransaction();
session.delete(changes);
session.beginTransaction().commit();
} catch (Exception e){
System.out.println("Erro ao excluir: "+e.getMessage());
session.beginTransaction().rollback();
}
}
