Cast fetch to join : error

#1

hello i have the following error ERROR: Invalid path: 'generatedAlias2.lib' when i use a join from a fetch cast, and i use this join to build an order

In advance, thank you for your answer,

versions :

  • hibernate 5.3.7.Final
  • db Oracle 11
  • jdk 8

example :

i want to make a fetch on the frns entity and a order on lib from the pays entity

Doesn’t work

CriteriaBuilder builder = session.getCriteriaBuilder();
CriteriaQuery query = builder.createQuery(Acfc.class);
Root root = query.from(Acfc.class);
Join<Acfc, Frns> joinAcfcfFrns = (Join) root.fetch(“frns”, JoinType.INNER);
Join<Frns, Pays> joinFrnsPays = joinAcfcfFrns.join(“pays”, JoinType.INNER);
query.orderBy(builder.asc(joinFrnsPays.get(“lib”)));
session.createQuery(query).setFirstResult(0).setMaxResults(10).getResultList();

Work’s fine without fetch cast

Join<Acfc, Frns> joinAcfcfFrns = root.join(“frns”, JoinType.INNER);
Join<Frns, Pays> joinFrnsPays = joinAcfcfFrns.join(“pays”, JoinType.INNER);

Work’s fine when all join are fetching

Join<Acfc, Frns> joinAcfcfFrns = (Join) root.fetch(“frns”, JoinType.INNER);
Join<Frns, Pays> joinFrnsPays = (Join) joinAcfcfFrns.fetch(“pays”, JoinType.INNER);

code snippet Entity Acfc

// frns
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "FRNS", nullable = false)
private Frns frns;

code snippet Entity Frns

@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "PAYS", nullable = false)
private Pays pays;
