Model unicode and Foreign key

[FedorFL]

possible bug:

class aModel(Model):
	name = models.CharField(_('name'), null=True, max_length=64, blank=True, default=None)

class bModel(Model):
        aLink = models.ForeignKey(aModel, null=False, blank=False)
        def __unicode__(self):
		return u'%s' % (self.aLink.name)

gives error at admin:

RelatedObjectDoesNotExist at ....
bModel has no aLink.

same for

        def __unicode__(self):
		return u'%s' % str(self.id)

but works with

        def __unicode__(self):
		return u'%s' % (self.id.aLink.name)

is it correct?

Which page gives the error and what is the full traceback?
