          Still have the problem with new release 1.3.9. It happened when I use selectize widget and when I use active search in the widget and it tries to get answer from backend to get new list of options. 

The problem appears in:

class FormCollection(BaseFormCollection, metaclass=FormCollectionMeta):
"""
Base class for a collection of forms. Attributes of this class which inherit from
django.forms.forms.BaseForm are managed by this class.
"""
def get_field(self, field_path):
path = field_path.split('.', 1)
key, path = path
return self.declared_holders[key].get_field(path)

self.declared_holders[key].get_field(path) return KeyError:'0'

I'm sorry to disturb you, but could you tell me is there a problem with selectize widget when we are using it in form collections or it's only my problem? :)

Is there a setup where I can reproduce this?

[amikphoto]

you could add selectize widget to your test application in any form collection. For best expirience you should set max_prefetch_choices to 2 (from 250). It helps to find problem with working with backend.

This has been fixed now and will work in version 1.3.10

Thank you very much! Yes, the problem is solved. Going to see next one :)

Thanks for reporting. Understanding other's use-cases help me to improve the stability of the project.
