I might be having a similar issue. I have simplified this issue down
to a simple example listed below. If I run with the current comments,
everything works fine, and the Collections are loaded. If I uncomment
"foo1" or "foo2", the Collections no longer load (they are null). If
I uncomment the constructor where I add values to the list, everything
works fine again.
@PersistenceCapable(identityType = IdentityType.APPLICATION)
public class Player2 {
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
public Long key;
//@Persistent
//private Long foo1; //Cause Collection issue
//@Persistent
//private String foo2; //Causes Collection issue
@Persistent
private Key foo3; // This works
@Persistent(defaultFetchGroup = "true")
private Set<Long> longSet = new HashSet<Long>();
@Persistent(defaultFetchGroup = "true")
private List<Long> longList = new ArrayList<Long>();
@Persistent(defaultFetchGroup = "true")
private Set<String> stringSet = new HashSet<String>();
@Persistent(defaultFetchGroup = "true")
private List<String> stringList = new LinkedList<String>();
@Persistent(defaultFetchGroup = "true")
private Set<Key> keySet = new HashSet<Key>();
@Persistent(defaultFetchGroup = "true")
private List<Key> keyList = new LinkedList<Key>();
public Player2() {
//Adding to the List Fixes Collection issue
//longSet.add(1234l);
//longList.add(1234l);
//stringSet.add("1234l");
//stringList.add("1234l");
//keySet.add(KeyFactory.createKey(Player2.class.getSimpleName
(), "[email protected]"));
//keyList.add(KeyFactory.createKey(Player2.class.getSimpleName
(), "[email protected]"));
}
}
I have started another thread in case this is a different issue, but
wanted to post here because this thread is listed in a ticket.
Thanks,
Jeff
