Pinaki,
Thank you for looking at this. Here you are:
First, here's the modified method. (I printed out qDef in three different
places)
public List<E> findByExample(
@NotNull E exampleInstance,
@Nullable Attribute<E,?>[] excludeProperty,
SingularAttribute<E,?>... orderFields
) throws DAORuntimeException {
EntityManager entityManager = JpaUtil.getEntityManager();
OpenJPACriteriaBuilder builder = (OpenJPACriteriaBuilder)
entityManager.getCriteriaBuilder();
CriteriaQuery<E> qDef = builder.createQuery(persistentClass);
System.err.println("qDef a = " + qDef);
Root<E> from = qDef.from(persistentClass);
qDef.select(from);
qDef.where(builder.qbe(from, exampleInstance, excludeProperty));
System.err.println("qDef b = " + qDef);
List<Order> orderList = makeOrderList(builder,
qDef.from(persistentClass), orderFields);
if (!orderList.isEmpty()) {
qDef.orderBy(orderList);
}
System.err.println("qDef c = " + qDef);
Query query = entityManager.createQuery(qDef);
return (List<E>) query.getResultList();
}
I ran it twice. The first time was with no order specified, where it worked
correctly. The second time was with an order.
Here are the first correct results:
qDef a = SELECT * FROM
qDef b = SELECT c FROM company c WHERE c.name = 'ACME'
qDef c = SELECT c FROM company c, company c WHERE c.name = 'ACME'

Here are the second incorrect results:
qDef a = SELECT * FROM
qDef b = SELECT c FROM company c WHERE c.name = 'ACME'
qDef c = SELECT c FROM company c, company c WHERE c.name = 'ACME' ORDER BY
c.name

The qDef values look right. I don't know why it added a join to the actual SQL.
