http://www.doctrine-project.org/jira/browse/DDC-3619 When using SoftDeleteable doctrine extension, an entity can be scheduled for deletion, then persisted before flushing. In such a case, the entity was removed from the unit of work identity map and no reference was hold. This could lead to spl_object_hash collisions, and prevent another, new entity to be persisted later. This fix makes sure the unit of work identity map holds a reference to the entity after it has been soft-deleted.
Doctrine 2 ORM
Doctrine 2 is an object-relational mapper (ORM) for PHP 5.3.2+ that provides transparent persistence for PHP objects. It sits on top of a powerful database abstraction layer (DBAL). One of its key features is the option to write database queries in a proprietary object oriented SQL dialect called Doctrine Query Language (DQL), inspired by Hibernates HQL. This provides developers with a powerful alternative to SQL that maintains flexibility without requiring unnecessary code duplication.
