[hibernate-issues] [Hibernate-JIRA] Created: (HHH-5133) Refresh causes assertion failure on OneToMany (cascaded) property with new members
Refresh causes assertion failure on OneToMany (cascaded) property with new members
----------------------------------------------------------------------------------
Key: HHH-5133
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5133
Project: Hibernate Core
Issue Type: Bug
Components: core
Affects Versions: 3.5.1
Environment: Oracle 10g
Reporter: Ramon Casha
An entity with a OneToMany property (cascade=all) is retrieved from the DB, then a NEW
instance is added to the OneToMany property. If you call refresh on the parent it will
give an assertion failure because Hibernate tries to refresh the added object although it
is not persistent.
eg:
class Child { }
class Parent {
@OneToMany(cascade=ALL) List<Child> children;
}
Parent p = em.find(Parent.class, 1);
p.children.add(new Child());
em.refresh(p);
This causes:
