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:

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
