[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-3218) ManyToOne Persisting Cascade in Embeddable

ManyToOne Persisting Cascade in Embeddable ------------------------------------------ Key: HHH-3218 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3218 Project: Hibernate Core Issue Type: Bug Affects Versions: 3.2.6, 3.5.1 Environment: Java version: java version "1.6.0_04" Java(TM) SE Runtime Environment (build 1.6.0_04-b12) Java HotSpot(TM) Client VM (build 10.0-b19, mixed mode, sharing) Oracle Version: Oracle9i Enterprise Edition Release 9.2.0.8.0 - Production PL/SQL Release 9.2.0.8.0 - Production "CORE 9.2.0.8.0 Production" TNS for Linux: Version 9.2.0.8.0 - Production NLSRTL Version 9.2.0.8.0 - Production hibernate: 3.2.6.ga hibernate-annotations: 3.3.1.ga hibernate-commons-annotations: 3.3.0.ga hibernate-entitymanager: 3.3.1.ga Reporter: Endre Jeges Assignee: Gail Badner Fix For: 4.0.0.next Attachments: pairTest.zip Hello, I have found something that is a bit strange. For @ManyToOne association properties in an @Embeddable class the cascade PERSIST, SAVE-UPDATE option is not working well (not sure for the other cascade types), if the entities associated with ManyToOne are transient. I have created a unit test to check it and I have it attached to this issue. It is a maven2 project, and needs Oracle to run it. If I save the associated entites, then everything works fine, also the data structure is created well. I have checked the forums and found similar problems, maybe they can help more then my post: http://forum.hibernate.org/viewtopic.php?t=965238 http://forum.hibernate.org/viewtopic.php?t=976534 http://forum.hibernate.org/viewtopic.php?t=978112 http://forum.hibernate.org/viewtopic.php?t=978138 http://forum.hibernate.org/viewtopic.php?t=983766 http://forum.hibernate.org/viewtopic.php?t=983780 http://forum.hibernate.org/viewtopic.php?t=983868 Details: @Entity class CodedPairHolder { @Id private Long id; @Column(name = "CODE", nullable = false, unique = true, updatable = false, length = 256) private String code; @CollectionOfElements @JoinTable(name = "CODED_PAIR_HOLDER_PAIR_SET", joinColumns = @JoinColumn(name = "CODED_PAIR_HOLDER_ID")) private final Set<PersonPair> pairs = new HashSet<PersonPair>(0); ........ constructors getters equals hashCode } @Embeddable class PersonPair { @ManyToOne(optional = false, fetch = FetchType.LAZY, cascade = { CascadeType.PERSIST, CascadeType.MERGE, CascadeType.REFRESH }) @Cascade( { org.hibernate.annotations.CascadeType.PERSIST, org.hibernate.annotations.CascadeType.MERGE, org.hibernate.annotations.CascadeType.REFRESH, org.hibernate.annotations.CascadeType.SAVE_UPDATE, org.hibernate.annotations.CascadeType.REPLICATE, org.hibernate.annotations.CascadeType.EVICT }) @JoinColumn(name = "LEFT_PERSON_ID", nullable = false, updatable = false) private Person left; @ManyToOne(optional = false, fetch = FetchType.LAZY, cascade = { CascadeType.PERSIST, CascadeType.MERGE, CascadeType.REFRESH }) @Cascade( { org.hibernate.annotations.CascadeType.PERSIST, org.hibernate.annotations.CascadeType.MERGE, org.hibernate.annotations.CascadeType.REFRESH, org.hibernate.annotations.CascadeType.SAVE_UPDATE, org.hibernate.annotations.CascadeType.REPLICATE, org.hibernate.annotations.CascadeType.EVICT }) @JoinColumn(name = "RIGHT_PERSON_ID", nullable = false, updatable = false) private Person right; ........ constructors getters equals hashCode } @Entity class Person { @Id private Long id; @Column(name = "NAME", nullable = false, unique = true, updatable = false, length = 256) private String name; ........ constructors getters equals hashCode } The error message is: org.hibernate.TransientObjectException: object references an unsaved transient instance - save the transient instance before flushing: Person Regards, jeges
