PrePersist is called on object although no merge/persist operation is cascaded/applied -------------------------------------------------------------------------------------- Key: HHH-6958 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-6958 Project: Hibernate ORM Issue Type: Bug Components: core Affects Versions: 4.0.0.CR2, 4.0.0.Final Environment: JBoss AS 7 Reporter: Benjamin Diedrichsen Priority: Critical Labels: jpa2 The scenario: A persistent instance of class A is loaded. A transient object of type b is created and with it a transient object of type c. Then the merge operation is invoked on A. The unexpected behaviour now is that the @PrePersist method on C is called although the causing merge-operation does not apply (not cascaded from B to C) and is actually not executed on the object (--> C will not be persisted to the database). Why is PrePersist invoked for C if no persist or merge operation is actually cascaded? Class A{ @OneToOne(cascade = CascadeType.ALL, optional = true, orphanRemoval = true) private B b; } Class B{ @ManyToOne(optional = false, cascade={CascadeType.PERSIST}) private C c; } Class C{ // some basic attributes here }
