14760	Admin inlines with file/image field fails to save_as	paulos	nobody	"How to reproduce:
 * declare an admin inline which ""model"" property referes to a model containing an image field and another char field
 * declare a parent ModelAdmin having save_as=True
 * in the admin, create and save a new parent with one or more inlines
 * try to save_as

Result:
 * the form does not validate, image or file field will be empty with error: ""This field is required."", extra inlines gone.
 * if you try to upload other file admin blows up with ValueError: invalid literal for int() with base 10: ''

Test case:
- dummy/models.py
{{{
from django.db import models

class Foo(models.Model):
    name = models.CharField(max_length=30)

class Bar(models.Model):
    parent = models.ForeignKey(Foo)
    title = models.CharField(max_length=30)
    img = models.ImageField(upload_to='testpath')
}}}
- dummy/admin.py
{{{
from django.contrib import admin
from bugtest.dummy.models import *

class BarInline(admin.StackedInline):
    model = Bar

class FooAdmin(admin.ModelAdmin):
    inlines = (BarInline,)
    save_as = True

admin.site.register(Foo, FooAdmin)
}}}
