New-admin problem

[[EMAIL PROTECTED]]

Hi has anyone seen the following error when using the new admin branch?

'AutoField' object has no attribute 'get_db_column'

I have the following model defined and can't create a new object for
any of the classes even the super simple PropertyType

Thanks
Charlotte

class Item(meta.Model):
    description = meta.CharField(maxlength=250, core=True)
    type = meta.CharField(maxlength=100, core=True)
    serial_number = meta.CharField(maxlength=30, blank=True, null=True)

    class META:
           admin = meta.Admin()

class PropertyType(meta.Model):
    name = meta.CharField(maxlength=100)

    class META:
           admin = meta.Admin()


class ItemProperty(meta.Model):
    item = meta.ForeignKey(Item, edit_inline=meta.TABULAR,
num_in_admin=6)
    propertytype = meta.ForeignKey(PropertyType, core=True)
    value = meta.CharField(maxlength=100, core=True)

    class META:
           admin = meta.Admin()
