[FIXED] Deleted object would be re-saved by cascade (remove deleted object from associations)

Issue

I have the following two entities:

1- PlayList:

@OneToMany(fetch = FetchType.EAGER, mappedBy = "playlist", orphanRemoval = true, cascade =   CascadeType.ALL)
@OrderBy("adOrder")
private Set<PlaylistadMap> PlaylistadMaps = new HashSet<PlaylistadMap>(0);

• CascadeType.ALL: is needed for save and update on the PlaylistadMap collection when saving or updating the playlist entity.
• orphanRemoval = true: is needed when deleting the playlist entity, the PlaylistadMap references should be deleteed too.

2- PlaylistadMap:

@ManyToOne(fetch = FetchType.EAGER)
@JoinColumn(name = "fk_playlist", referencedColumnName = "pkid", nullable = false)
private Playlist playlist;

when deleting a playlist by using getCurrentSession().delete(); i am getting the following exception:

org.springframework.dao.InvalidDataAccessApiUsageException: deleted object would be re-saved by cascade (remove deleted object from associations): [com.xeno.advertisingsuite.web.domain.PlaylistadMap#6]; nested exception is org.hibernate.ObjectDeletedException: deleted object would be re-saved by cascade (remove deleted object from associations): [com.xeno.advertisingsuite.web.domain.PlaylistadMap#6]
