Hello,

This one's tricky. It may be simplest to just _create_ the empty inline ModelA's so they appear. Otherwise, you'll need to look at the ModelA's that exist in the database and figure out which ones needed to be added to the initial data.

You'll likely need to add the initial data using the get_formsets_with_inlines hook.

https://docs.djangoproject.com/en/dev/ref/contrib/admin/#django.contrib.admin.ModelAdmin.get_formsets_with_inlines

And you can always peak at the source code to get a better feel for what's going on :)
