26681	save_as=True and inlines in ModelAdmin raises ValidationError	Andreas Stocker	nobody	"{{{ModelAdmin}}} raises a {{{ValidationError}}} exception when trying to save after the first time trying to save with ""Save as new"" failed with form errors. The exception message is {{{[u""'' value must be an integer.""]}}}

**Steps to reproduce:**

1.) Register a ModelAdmin with inlines:
{{{#!python
class MyStackedInline(admin.StackedInline):
    model = MyInlineModel
    extra = 1

class MyAdmin(admin.ModelAdmin):
    inlines = [MyStackedInline, ]
    save_as = True

admin.site.register(MyModel, MyAdmin)
}}}

2.) Go to the admin panel, open an existing {{{MyModel}}} object and change the form contents in a way that causes form errors (e.g. keep an required field blank).
3.) Click on the ""Save as new"" button.
4.) The form now shows the validation errors. Fix them and click on the ""Save and add another"" button. Notice there is no ""Save as new"" button any more, though {{{save_as=True}}}.
5.) The admin panel now raises the {{{ValidationError}}} exception.
