There are two entities: Post and Comment.
Post has collection of comments that are selected in subselect query:
{{ @OneToMany(mappedBy = "post", fetch = FetchType.EAGER, cascade = CascadeType.MERGE)
@Fetch(value = FetchMode.SUBSELECT)
private List<Comment> comments;}}
When Post entities are selected by CriteriaQuery with specific 'orderBy' expression that contains params (see fragment below), exception 'SQLException: Parameter index out of range (1 > number of parameters, which is 0).' is thrown.
{{Order order = builder.desc(builder.coalesce(root.get("name"), "default_name"));
query.orderBy(order);}}
