i've an app that adds and removes items from a JList.
When the app opens up, the are allready several items in that JList:
a
b
c
If i
add item
d and then
persist it and after that i try to
delete it, i get that error msg, but if i try to delete
any other item from the JList, it works perfectly ok.
I'm using hibernate2.1.3, MySql 4.0.12 nt and sdk1.4.2_04.
the code i use to add:
Code:
//...
Detalhe detalhe = new Detalhe();
String nova = (String) visual.lstTipificada.getSelectedValue();
detalhe.setEstrategia(nova);
rel.getTurma().adicionarDetalhe(detalhe);
//...
The code i use to delete:
Code:
//...
Detalhe detalhe = (Detalhe) visual.lstDetalhe.getSelectedValue();// ERROR here
rel.getTurma().removerDetalhe(detalhe);
//...
the code i use to update:
Code:
//...
sess.saveOrUpdate(rel);
sess.flush();
sess.refresh(rel);
t.commit();
HibernateUtil.closeSession();
I have an object
Relatorio that is composed of two objs:
Turma and
Disciplinas.
Turma has a child called
DetalheAnd its a
detalhe i'm trying to delete.
