I observed a strange situation using JPA in case of detached object. If I want to use the Tenant (see bellow) object in JSF page accept the tenantId field all fields are NULL. But before the return statement if I access any of the member variable of Tenant Object it works file. I tried with FetchType.Eager, but no luck.
Is it a known feature or BUG? This is my entity class a Tenant has one or more user. @Entity public class Tenant{ @OneToMany(mappedBy="tenant", cascade=CascadeType.ALL) Collection<User> hmsUserList = new ArrayList<User>(); ..... } @Entity public class User{ @ManyToOne @JoinColumn(name="tenant_id") private Tenant tenant; .... } My function returns the Tenant Object as; public Tenant myFunction(){ User user = em.find(User.class, ID); //if add the bellow line it works // user.getTenant().getName(); return user.getTenant(); } --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
