Hi,
I have following classes. I am creating a country object first and it get
persisted, then i read its key field and i get some value.
Basically i start a transaction and persist it close/commit the transaction.
then i create a State and set Country for state object as the country(reload
the country in this transaction) i just created.
After i save State object using
pm.makePersistent(state);
I try to read id field(Key) from state object, but its coming as null and
data(state object) is not persisting.
Can you please advise me if i am doing anything wrong.
Following are the classes
@PersistenceCapable(identityType = IdentityType.APPLICATION)
public class Country implements BaseObject{
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Key id;
@Persistent
private String name;
@Persistent
private long stateCount;
@Persistent(mappedBy = "country")
private List<State> states;
}
@PersistenceCapable(identityType = IdentityType.APPLICATION)
public class State implements BaseObject{
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Key id;
@Persistent
private String name;
@Persistent
private Country country;
@Persistent(mappedBy = "state")
private List<District> districts;
}
public interface BaseObject {
public Key getId();
public void setId(Key id);
}
Thanks,
Ravi
