Hello, everybody!
I try to achieve simple thing - storing a set of keys.
I have two classes:
@PersistenceCapable(identityType = IdentityType.APPLICATION)
public class Account {
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Key id;
@Persistent(mappedBy="account")
List<Label> labels = new ArrayList<Label>();
@Persistent
Set<Key> ids = new HashSet<Key>();
}
@PersistenceCapable(identityType = IdentityType.APPLICATION)
public class Label {
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Key id;
@Persistent
private Account account;
}
I created new Account
Account a = new Account();
then added two Labels to Account, then added Label's keys to ids set.
As result I have for ids:
[Account(1)/Label(4), Account(1)/Label(3)]
which looks correct.
Then I called
pm.makePersistent(a),
pm.close();
I created new instance of PersistenceManager and restore Account
object.
I get back two Labels, but their keys (ids set) is empty.
What did I do wrong?
Thank you,
Andrey
