[appengine-java] Datastore retrieve error

2009-10-23 Thread Gerd Saurer 

I have a object mapped to the Datastore that looks like:

@PersistenceCapable(identityType = IdentityType.APPLICATION)
public class SyncConfiguration {

@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Long id;

@Persistent
private Account account1;

@Persistent
private Account account2;

..
}

@PersistenceCapable(identityType = IdentityType.APPLICATION)
public class Account {

@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Key key;

@Persistent
private String email;

.
}

if i am now loading the object back from the store with

final SyncConfiguration syncConfig = pm.getObjectById
(SyncConfiguration.class, action.getSyncConfigId());

the fields account1 and account2 have the same instance.

Do i have to configure something in a different way or is it a bug?
