When saving a new top level of a nested table - Changing a field and saving twice is required.

[lukedupin]

When creating a new nested table, after clicking the Add new, at least one field needs to be changed, and "save and continue" must be clicked twice before a save happens.

Can I throw you guys a couple hundred bucks to fix these?

Having the same issue.

Did some digging. The saving breaks if there is multilevel nesting and the extra attribute in NestedStackedInline is set to 0. It means that the sub-sub-level forms do not get created. Attached some code to reproduce:

# models.py
from django.db import models

class A(models.Model):
    content = models.CharField(max_length=255)

class B(models.Model):
    content = models.CharField(max_length=255)
    a = models.ForeignKey(A)

class C(models.Model):
    content = models.CharField(max_length=255)
    b = models.ForeignKey(B)

#admin.py

from django.contrib import admin
from nested_inline.admin import NestedStackedInline, NestedModelAdmin
from someapp.models import A, B, C

class CAdmin(NestedStackedInline):
    model = C
    extra = 1

class BAdmin(NestedStackedInline):
    model = B
    inlines = [CAdmin]
    extra = 0 #  <-- This breaks the formset generation

class AAdmin(NestedModelAdmin):
    inlines = [BAdmin]
    model = A

admin.site.register(A, AAdmin)

I'll be more than happy to take part in solving this.

Nice find.

I ended up switching my nested plugin over to: django-nested-admin (2.1.8)

It doesn't support Tabular inline which is a shame, but it seems to work reliably otherwise.
