I saw old reference (3 years ago) to OneToMany Unidirectional (foreign key) not being implemented: https://groups.google.com/d/msg/doctrine-user/y8du6cafhdA/QnY_h8NjD10J
I don't see it in current documentation and have also tried using JPA 2.0 onetomany unidirectional annotations and they don't work on Doctrine 2.3.3.
So can I assume OneToMany Unidirectional is still not implemented?
