The @ContainedIn annotation doesn't work when I execute the Entitymanager.persist(): the fields regarding the "embedded field" are empty!
On update record indexing is correct.


The following code describe my domain:

Code:

public class Profile{
  private String surname;
...
}

@ClassBridge(name = "customIndexingClassBridge", impl = CustomIndexingClassBridge.class)
public class DangerousEvent{

  @OneToMany(mappedBy = "compositeKey.dangerousEvent", fetch = FetchType.LAZY)
  Set<DangerousEventLinkedProfile> profils;
...
}

@ClassBridge(name = "customIndexingClassBridge", impl = CustomIndexingClassBridge.class)
public class DangerousEventLinkedProfile{
  @Embedded
  private DangerousEventLinkedProfileID compositeKey = new DangerousEventLinkedProfileID();

  private String tag;
  ...
}

@Embeddable
public class DangerousEventLinkedProfileID{

  @ContainedIn
  @ManyToOne
  DangerousEvent dangerousEvent,
 
  @ContainedIn
  @ManyToOne
  Profile profile;

...
}


// TEST PROCEDURES

Code:
..
@PersistenceContect
EntityManager em;

// DONT WORK
public void wontWork(){
  DangerousEvent dangerousEvent = new DangerousEvent();
  Profile profile = new Profile();
  profile.setSurname('test surname');

  DangerousEventLinkedProfile link =  new DangerousEventLinkedProfile();
  link.getCompositeKey().setDangerousEvent(dangerousEvent);
  link.getCompositeKey().setProfile(profile);

  em.persist(link);

// The index misses "surname" field;

}

// WORK WELL
public void workAndIndexCorrectly(){
  DangerousEventLinkedProfile link = em.find(DangerousEventLinkedProfile.class , existingUUID);
  link.tag = 'test';
  em.merge(link);

// Index fills "surname" field;

}




Do you have any idea what could be the problem? I'm doing some mistake?

Hi darioc,
in your example the entity DangerousEventLinkedProfileID is marked as @ContainedIn -> DangerousEvent which simply means that on a change, the indexing process needs to refresh the Lucene Document for the DangerousEvent type.
The DangerousEvent however is marked with a @ClassBridge! The ClassBridge implementation completely overrides the indexing process.

So in your example it's correct to have the @ContainedIn marker to trigger indexing via your custom ClassBridge, but your implementation CustomIndexingClassBridge.class is responsible for adding all fields to the Lucene Document, even the embedded ones.

I hope we'll have time for implementing a combination of ClassBridge && annotations in Hibernate Search 6, but currently it's an either-or strategy.
