[hibernate-issues] [Hibernate-JIRA] Created: (HHH-6917) Persist deleted entity in collection which is not removed from collection

Persist deleted entity in collection which is not removed from collection ------------------------------------------------------------------------- Key: HHH-6917 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-6917 Project: Hibernate Core Issue Type: Bug Components: entity-manager Affects Versions: 3.6.9, 4.0.0.Final Environment: PostgreSQL 9.0.4, MySQL 5.5, Spring 3.1, JPA 2.0 Reporter: Wong D Attachments: delete-test-src.zip In one-to-many relationship, hibernate will not delete the entity from the collection if the entity is deleted from the outside and was not removed from the collection. For example, we have two classes: class A { @OneToMany(cascade=CascadeType.ALL) Collection<B> bs; } class B { @ManyToOne A a;} A has a collection of B, say b1, b2, b3. The following code will raise EntityNotFoundException: deleted entity passed to persist B#null for(B b : A.bs) { BService.delete(b); // No call to persist(A) } After we delete the b1, the deletion of b2 will cause the error. A complete test case attached. I found out before each query org.hibernate.event.def.AbstractFlushingEventListener class calls prepareEntityFlushes(EventSource session). If I delete one entity B but did not remove it from the collection A.bs, Hibernate will throw the exception "deleted entity passed to persist" when persisting A, even I did not call persist A. So the exception could be thrown any time (for example, it throws when I execute a SELECT query). I am expecting a transparent action that Hibernate will update the collection directly. BTW, I test eclipselink and it did not complain about deleted entity. -- This message is automatically generated by JIRA. For more information on JIRA, see: http://www.atlassian.com/software/jira
