CriteriaBuilder Parent multiselect with child object - parent-child

Question

I'm trying Build criteriaQuery with a parent child entities, I need to use multiselect for selected fields for parent and selected fields for child, not able to pull all the children with fields
#Data
#Entity
#NoArgsConstructor
#Table( name = "Orders" )
public class Orders {
#Id
#Column( name = "ORDER_ID" )
private String orderId;
...
#OneToMany(cascade= CascadeType.ALL, mappedBy = "order")
#NotFound(action = NotFoundAction.IGNORE)
private List<Contact> contacts;
...
}
#Data
#Entity
#NoArgsConstructor
#Table( name = "CONTACT" )
public class Contact {
#Id
#Column( name = "ORDER_ID" )
#ManyToOne(fetch = FetchType.LAZY)
#JoinColumn (name="ORDER_ID",referencedColumnName="ORDER_ID",insertable=false, updatable=false)
private Order order;
...
}
My Query implementation
List<String> fields ={"OrderId","OrderName","OrderDate"};
CriteriaBuilder cb = entityManager.getCriteriaBuilder();
CriteriaQuery<Tuple> cq = cb.createTupleQuery();
Root<Order> root = cq.from(Order.class);
ListJoin join = root.joinList("contacts");
Subquery<Contact> squery = criteriaQuery.subquery(Contact.class);
Root<Contact> contactRoot = squery.from(Contact.class);
Join<Contact, Order> join2 = contactRoot.join("order");
squery.select(contactRoot).where(criteriaBuilder.equal(join, root));
Predicate predicate = specification.toPredicate(root,cq, cb);
List<Selection<?>> selections=new ArrayList<>();
fields.forEach(field -> selections.add(root.get(field).alias(field)));
cq.multiselect(selections);
cq.where(predicate);
TypedQuery<Tuple> typedQuery=entityManager.createQuery(cq);
return typedQuery.getResultList();
I see the join is correct, but select clause is not including any children. Any one came across this>
