Hi,

To confirm the solution:

I have a scenario where I have a @OneToMany relationship (on object `Partenaire`) without the REMOVE cascade linked with @ManyToOne (on object `ConventionPartenaire`).

When I delete object `Partenaire`, it then tells me that it’s not possible to save object `ConventionPartenaire` because it holds a transient object (which is normal).

 ![image](https://canada1.discourse-cdn.com/flex035/uploads/hibernate/original/2X/b/bc4689f3e7f5ee9b8ef3fd50672f1a52276b62d8.png)

Is the solution to set the return variable to null by removing the association from `ConventionPartenaire` to `Partenaire` (`@PreRemove`) ?

Thank you !

```auto
@Entity
public class Partenaire {
  @OneToMany(mappedBy = "partenaire", fetch = EAGER, cascade = {REFRESH, PERSIST})
  private Set<ConventionPartenaire> conventions = new HashSet<>();

  @PreRemove
  public void preRemove() {
    conventions.forEach(this::removeFromConventions);
  }

  public boolean removeFromConventions(ConventionPartenaire conventionPartenaire) {
    conventionPartenaire.setPartenaire(null);
    return conventions.remove(conventionPartenaire);
  }
}

@Entity
public class ConventionPartenaire {
  @ManyToOne
  private Partenaire partenaire;
}

```

Yeah, that looks ok to me.
