[hibernate-issues] [Hibernate-JIRA] Created: (HHH-3008) Cascade delete does not work with unidirectional @OneToMany and @JoinTable
Cascade delete does not work with unidirectional @OneToMany and @JoinTable
--------------------------------------------------------------------------
Key: HHH-3008
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3008
Project: Hibernate3
Issue Type: Bug
Affects Versions: 3.2.5
Environment: Standalone entity manager (JavaSE 5.0).
H2 database.
Reporter: Daniel Dyer
A unidirectional one-to-many relationship defined as follows:
public class Owner
{
@OneToMany(cascade = CascadeType.ALL)
@JoinTable(name = "owner_element",
joinColumns = @JoinColumn(name = "owner_id",
nullable = false,
updatable = false),
inverseJoinColumns = @JoinColumn(name = "element_id",
nullable = false,
updatable = false))
private List<Element> elements;
// ...
}
Attempting to delete an instance of Owner should also delete all associated instances of
Element. Instead I get the following error:
SEVERE: Referential integrity constraint violation: FK56BBF9C487E817D:
PUBLIC.OWNER_ELEMENT FOREIGN KEY(OWNER_ID) REFERENCES PUBLIC.OWNER(ID) [23003-63]
This is because Hibernate attempts to delete the Owner row without first removing the rows
from the join table.
