I changed the relation declaration to use remote_side, but i get the
exact same stack trace on 0.5.4p2, and still no problem on 0.5.2.
Here is the modified relation declaration in the test code:
mapper(Entity,
entity_table,
polymorphic_on = entity_table.c.entity_type,
polymorphic_identity = EntityType.Entity,
properties = {
'creator':
relation(Client,
collection_class = set,
primaryjoin = entity_table.c.id_creator ==
entity_table.c.id,
foreign_keys = [entity_table.c.id_creator],
remote_side = [entity_table.c.id_creator],
backref = sqlalchemy.orm.backref
('entities_created',
foreign_keys =
[entity_table.c.id],
remote_side =
[entity_table.c.id]))})
