Hey Andreas --
I actually ran into this same problem myself today. It appears to be
a bug in the admin changelist view; until I get a chance to actually
track it down you can work around it by adding a "ordering" option to
your META.admin::
class FirstChild(meta.Model):
...
class META:
admin = meta.Admin(ordering=('myvar',))
...

I'm trying to order a class by its parent, but apparently I'm doing
something wrong. The code I use:
class ParentClass(meta.Model):
somevar = meta.CharField(maxlength=100)
def __repr__(self):
return self.somevar
class META:
admin = meta.Admin()
ordering = ['somevar']
class FirstChild(meta.Model):
theparent = meta.ForeignKey(ParentClass)
myvar = meta.CharField(maxlength=100)
def __repr__(self):
return self.myvar
class META:
admin = meta.Admin()
order_with_respect_to = 'theparent'
I can add ParentClass- and FirstChild-Items in Admin and viewing the
ParentClass-List works, too. Viewing the FirstChild-List, however,
results in an error:
There's been an error:
Traceback (most recent call last):

Any ideas how I can get that to work?
