While adding an entity of class %s with an ID hash of "%s" to the identity map,
another object of class %s was already present for the same ID. This will trigger
an exception in ORM 3.0.
IDs should uniquely map to entity object instances. This problem may occur if:
- you use application-provided IDs and reuse ID values;
- database-provided IDs are reassigned after truncating the database without
clearing the EntityManager;
- you might have been using EntityManager#getReference() to create a reference
for a nonexistent ID that was subsequently (by the RDBMS) assigned to another
entity.
Otherwise, it might be an ORM-internal inconsistency, please report it.
To opt-in to the new exception, call
\Doctrine\ORM\Configuration::setRejectIdCollisionInIdentityMap on the entity
manager's configuration.
