25587	"Django fails, when trying to save object ""as new"" with inlines objects and form validation errors."	user0007	nobody	"Let's assume that I have one existing object in Django Admin with some related objects (inlines). When I try to create a clone (by clicking on ""Save as new""), but there are some validation errors, Django will fail, after clicking ""Save and continue editing"".

Everything works without inlines objects.

Error:

{{{
django.db.models.fields in get_prep_value
ValueError: invalid literal for int() with base 10: ''
}}}
