SQL> ALTER SYSTEM SET DB_RECOVERY_FILE_DEST_SIZE = 10G;

System altered.

Now open the database.

SQL> alter database open;

Database altered.

Hibernate - A collection with cascade=”all-delete-orphan” was no longer referenced by the owning entity instance

      public void save(ActionEvent event) {  
           dao = new InboxFinanceiroDao<Inbox>(HibernateUtil.getSession(),Inbox.class);  
           desativarTab = false;  
           try {  
                dao.save(inbox);  
                dao.refresh(inbox); // Adicione essa linha após persistir o objeto.
           } catch (Exception e) {  
                
           }

Hibernate: Ordenar lista por propriedade de objeto.

Ordenar lista por propriedade de objeto.

Deve-se utilizar o nome do join criado pelo Hibernate (posicaoflp1_). Para ver o nome basta ativar a exibição de SQL no arquivo hibernate.conf.

<property name="hibernate.show_sql">true</property>
<property name="hibernate.format_sql">true</property>

public class Processo implements Serializable,Cloneable {

     @OrderBy("posicaoflp1_.ordem desc")
     @NotAudited
     protected Collection<Followup> followup;
}

public class Followup implements Serializable, Cloneable {

@OneToOne
@JoinColumn(name="posicaoflp_id")
private PosicaoFlp posicaoFlp;
}

public class PosicaoFlp implements Serializable{
     private Integer ordem; // Ordenar por esse campo
}


SQL gerada pelo Hibernate: left outer join posicaoflp posicaoflp1_ on followup0_.posicaoflp_id=posicaoflp1_.id
