Ling Lin commented on HHH-5529:
-------------------------------
I am having this exact same problem! Is there a work around? I cant work out a way to solve this problem without manually pulling out each object from the database and removing each object from the element collection!

> Key: HHH-5529
> URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5529
> Project: Hibernate Core
> Issue Type: New Feature
> Components: entity-manager
> Affects Versions: 3.3.2, 3.5.5, 3.6.0.Beta4
> Environment: Hibernate 3.5.x, all database, all platforms.
> Reporter: Pascal Thivent
> Attachments: HHH-XXX.tar.gz

> I have an entity with a collection of basic elements mapped with @ElementCollection:
> {code}
> @Entity
> public class Foo {
> @Id @GeneratedValue
> private Long id;
> @ElementCollection
> @Column(name = "bar_column")
> @CollectionTable(name = "Bar")
> private Set<String> bars = new HashSet<String>();
> public Long getId() { return id; }
> public void setId(Long id) { this.id = id; }
> public Set<String> getBars() { return bars; }
> public void setBars(Set<String> bars) { this.bars = bars; }
> }
> {code}
> A bulk delete on this entity fails due to constraint violation on the collection table (Hibernate ignores the collection table).
> I don't think that the following cascading restriction from the JPA 2.0 specification applies:
> {quote}
> h3. 4.10 Bulk Update and Delete Operations
> ...
> A delete operation only applies to entities of the specified class and its subclasses. It does not cascade to related entities.
> {quote}
> In other words, Hibernate should handle the collection table as we have no way to bulk delete the basic elements from the collection table.
> I have attached a test case allowing to reproduce the issue.
