Example of Nested Properties from JPAContainer manuel doesn't work for me

Vaadin 6 / 7 / 8 Framework Data Binding

I tested out following example from JPAContainer manual:

@Entity
public class Person implements Serializable {

	@Id
	@GeneratedValue(strategy=GenerationType.IDENTITY)
	private long id;

	private String firstname;

	private String lastname;

	private long version;
	
	@Embedded
	private Address address;
	
    public Person() {
    }
	// setter and getter

@Embeddable
public class Address implements Serializable, Cloneable {

	private String postalcode;

	private String postoffice;

	private String street;

    public Address() {
    }
	// setter and getter

When setting table.setContainerDataSource(myEntityContainer) EclipselLink throws an Exception with following SQL:

Query: ReadObjectQuery(name="readObject" referenceClass=Person sql="SELECT ID, FIRSTNAME, LASTNAME, VERSION, POSTALCODE, POSTOFFICE, STREET FROM PERSON WHERE (ID = ?)")

No wonder that im getting an Exception, columns street, postalCode and postOffice cant be fetched from Person table.

What do I have to do to get this working? :wacko:
