Problema con relaciones en sqlobject

[Luis Miguel Morillas]

Alquien ve algo mal en este ejemplo?

from sqlobject import *
connection_string="sqlite:/:memory:"
connection = connectionForURI(connection_string)
sqlhub.processConnection = connection

class Clasea(SQLObject):
    valor = StringCol()
    relaciones = ForeignKey('Claseb')

class Claseb(SQLObject):
    valor = StringCol()
    relacion = MultipleJoin('Clasea')

Clasea.createTable()
Claseb.createTable()

b1 = Claseb(valor='hola')
a1 = Clasea(valor='adios', relaciones= b1)

>>> a1.relaciones
<Claseb 1 valor='hola'>
>>> b1.relacion
 1/QueryAll:  SELECT id FROM clasea WHERE claseb_id = 1
 1/QueryR  :  SELECT id FROM clasea WHERE claseb_id = 1
 1/COMMIT  :  auto

pysqlite2.dbapi2.OperationalError: no such column: claseb_id


¿Por qué busca el atributo claseb_id?
