Given the following classic OneToMany relationship between a blog post and its comments:

// parent entity
@Entity
@Table(name = "post")
public class Post {

    @Id
    private Long id;

    @OneToMany(mappedBy = "post", cascade = CascadeType.ALL, orphanRemoval = true)
    private List<PostComment> comments = new ArrayList<>();
}

// child entity
@Entity
@Table(name = "post_comment")
public class PostComment {

    @Id
    private Long id;

    @ManyToOne
    @JoinColumn(name = "post_id", referencedColumnName = "post_id")
    private Post post;
}

Now, our database provides an additional view joining several other tables. Let’s call it view_post. The list of post comments should be part of this view as modeled below:

@Entity
@Immutable
@Table(name = "view_post")
public class PostView {

    @Id
    private Long id;

    // other fields omitted...

    @OneToMany(mappedBy = "post")
    private List<PostComment> comments;
}

This however doesn’t work as clearly indicated by the exception:

Association 'ViewPost.comments' is 'mappedBy' a property named 'post' which references the wrong entity type 'Post', expected 'ViewPost'

I cannot find a way to model the entity representing the view.
