JDO Inheritance and generic declaration error #229

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
Declare a super-class as follow

@PersistenceCapable(identityType = IdentityType.APPLICATION, detachable = 
"false")
@Inheritance(strategy = InheritanceStrategy.SUBCLASS_TABLE)
public class Person<T extends Entity> implements Serializable {

    @PrimaryKey
    @Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
    @Extension(vendorName = "datanucleus", key = "gae.encoded-pk", value = "true")
    protected String encodedKey;
    @Persistent
    protected T owner;

and the following subclasses

@PersistenceCapable(identityType = IdentityType.APPLICATION, detachable = 
"false")
public class Client extends Person implements Serializable {

    @Persistent
    private String name;

@PersistenceCapable(identityType = IdentityType.APPLICATION, detachable = 
"false")
public class User extends Person<Company> implements Entity {

    @Persistent
    private String firstName;
    @Persistent
    private String lastName;
    @Persistent
    private String login;
    @Persistent
    private transient String password;
    @Persistent(mappedBy = "owner")
    @Element(dependent = "true")
    private transient List<Client> clients = new ArrayList<Client>();

try to make a user persistent

declare this another class and try to make it persistent

@PersistenceCapable(identityType = IdentityType.APPLICATION, detachable = 
"false")
public class Company implements Entity, Serializable {

    @PrimaryKey
    @Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
    private Long id;
    @Persistent
    private String name;
    @Persistent
    private Date dischargeDate;
    @Persistent
    private Date lowDate;
    @Persistent(mappedBy = "owner")
    @Element(dependent = "true")
    private transient List<User> users = new ArrayList<User>();
    @Persistent(mappedBy = "owner")
    @Element(dependent = "true")
    private transient List<Client> clients = new ArrayList<Client>();

what I got is no errors neither log output for the User class, but when I tried 
to persist a Company, I got the following error
