and
form validation errors.

-------------------------------+--------------------
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: ''
}}}
