I'm trying to get the PluralAttributePath from a collection defined in a MappedSuperclass
{code}
@Entity
public class Person extends PersonBase {
@Basic
private String name;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
{code}
{code}
@MappedSuperclass
public abstract class PersonBase {
@Id
private String id;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
@OneToMany()
private Set<Address> addresses = new HashSet<Address>();
public Set<Address> getAddresses() {
return addresses;
}
public void setAddresses(Set<Address> addresses) {
this.addresses = addresses;
}
}
{code}
Executing the following
{code}
criteriaQuery = criteriaBuilder.createQuery(Person.class);
root = criteriaQuery.from(Person.class);
Path<?> pathAddresses = root.get("addresses");
{code}
throws the exception
{noformat}
