Hi, i´m trying to save some date in my GAE app but this error appear
when I do de makePersistant of my object.
at the end of this mail you can see that in Service Class there are
one-to-one and 2 one-to-many relationships,.

My class are:
@PersistenceCapable(identityType = IdentityType.APPLICATION,

public class Service implements Serializable {

private static final long serialVersionUID =

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

@Persistent
private boolean active;
@Persistent
private String stateDescription;
/*Relationship Attributes*/
@Persistent
private Owner owner;
@Persistent
private Company company;
@Element(dependent = "true")
private List<Version> versions;
@Persistent
private Fichero iconFile;
......
}
@PersistenceCapable(identityType = IdentityType.APPLICATION,

public class Fichero implements Serializable {
private static final long serialVersionUID = -4568341150599424882L;

@PersistenceCapable(identityType = IdentityType.APPLICATION,

@Persistent
private Fichero zipFile;
@Persistent
private Fichero xmlModified;
@Element(dependent = "true")
private List<Fichero> recursos;
@Persistent

.....
}
The problem is with Fichero Class as you can see in the error Stack.
As you can see, in Service Class there are one-to-one and 2 one-to-
many relationships, I think this is the problem but, how can I do it??
