Hi,
I use Hibernate 3.6.4.
I have 2 basic entities "Parent" and "Child" with bidirectional orphanRemoval OneToOne association between them.
PropertyAccessException is thrown when I want to remove Child entity from Parent.
...
parent.setChild(null);
entityManager.merge(parent);
entityManager.flush();
...
When I try the same code with eclipselink 2.1.0 everything is ok. Parent has "null" child and child entity is deleted from db.
I can send by email simple working maven project with unittest for both jpa providers.
Code:
