Any suggestions for how to fix this problem? I get the following stack trace
when I use makePersistent() on a class. It goes away if I add serialized to
one of its field's annotation; i.e., change the annotation from
@Persistent(defaultFetchGroup = "true", mappedBy = "facility")
private Set<WaitlistEntry> waitlistEntries = new HashSet<WaitlistEntry>(0);
to
@Persistent(serialized = "true", defaultFetchGroup = "true", mappedBy =
"facility")
private Set<WaitlistEntry> waitlistEntries = new HashSet<WaitlistEntry>(0);
This is in the Facility class, the parent class. Taking out defaultFetchGroup
and mappedBy doesn't make any difference.
All of the classes that are persisted start with, for example,
@PersistenceCapable(identityType = IdentityType.APPLICATION, detachable =
"true")
public class WaitlistEntry implements Serializable, Comparable<WaitlistEntry> {
All of the other @Persistent annotated fields in the classes are on the
DataNucleus list (Calendar, Integer, etc.)
When I make the Set of WaitlistEntry serialzed=true then it's not persisted by
itself and I can't do any queries on it.
