ImageField with a ForeignKey disappears from the db

[anonymous]

model (basicly the example from the docs, think BlogPost and Comments, but comments are images (perhaphs it's enough for them to have images)), my model:

class Offer(models.Model):
    name = models.CharField()
    ...
    class Admin:pass

class OfferImage(models.Model):
    off = models.ForeignKey(Offer, edit_inline=models.STACKED, num_in_admin=3)
    image = models.ImageField(upload_to='photos', inline_edit )
 

(recent svn version)

1. I can create an Offer with say, two images.
2. I can add an image to an offer if I define Admin class for images

*BUT*

3. saving an offer in the admin interface causes the images to disapear from the db - seriously weird stuff

I didn't do any extensive testing (like if it happens while playing around in the interpreter too. The FileField is in the "stable" tarball versions, so I'm *guessing* this is specific to image's (although - again - didn't try it)

ok, so this is wrong, becouse there's no core=True defined. If that's indeed why the images are disapearing from the db, then i suppouse there should be some warning issued when there's no core=True field.
