Since this property was introduced
I have this error when persisting this kind of document in SAB:
MappingException: Class Doctrine\ODM\PHPCR\ReferrersCollection is not a valid document or mapped super class.
=> phpcr-odm should not try to persist a ReferrersCollection. this is just the inverse of the Reference annotation. as this is directional in phpcr, the ReferrersCollection should be immutable by the client.
