Using FlushModeType.AUTO, I would expect the persistence context to get flushed, whenever I have some pending updates on related entities contained in an entityGraphHinted HQL-query.
The entities are not themselves within the named query definition string, but because the NamedEntityGraph has includeAllAttributes set to true, all related entities are joined (and they are).
I found out by debugging however, that the QuerySpace only contained the toplevel entity (XBV_KLANT in the example below), and not the related ones (KlantrelatieJpa e.g.).
This resulted in the persistence context NOT getting flushed before query execution, even if there is a pending update on KlantrelatieJpa within the persistence context.
See autoFlushIfRequired method in org.hibernate.internal.SessionImpl
This seems a bug to me. All related entities should have been added to the QuerySpace in the process of creating and analyzing the AST, right?
Correct?
Example code:
@Table(name = "XBV_KLANT")
@Entity
@NamedQueries({
@NamedQuery(name = "KlantJpa.getById",
query = " * select DISTINCT k from KlantJpa k WHERE k.identificatie = :klantIdentificatie * ")
})
public class KlantJpa extends AbstractEntityJpa {
@Id
@Column(name = "KLT_IDENTIFICATIE", nullable = false)
private Long identificatie;
@Column(name = "KLT_SOUNDEXNAAM", nullable = false)
private String soundexnaam;
@OneToMany(mappedBy = "van", cascade = {CascadeType.ALL }, orphanRemoval = true)
private final Set<KlantrelatieJpa> vanKlantrelatie = new HashSet<KlantrelatieJpa>();
@OneToOne(mappedBy = "klant", cascade = {CascadeType.ALL }, orphanRemoval = true)
private PersoonsGegevensGbaJpa persoonsGegevensGBA;
@OneToOne(mappedBy = "klant", cascade = {CascadeType.ALL }, orphanRemoval = true)
private PersoonsGegevensNietGbaJpa persoonsGegevensNietGBA;
@OneToOne(mappedBy = "klant", cascade = {CascadeType.ALL }, orphanRemoval = true)
private AdresGegevensGbaJpa adresGegevensGBA;
@OneToOne(mappedBy = "klant", cascade = {CascadeType.ALL }, orphanRemoval = true)
private AdresGegevensNietGbaJpa adresGegevensNietGBA;
@OneToOne(mappedBy = "klant", cascade = {CascadeType.ALL }, orphanRemoval = true)
private AdresGegevensBuitenlandJpa adresGegevensBuitenlandJpa;
