Hi,
On our system we are using django-autocomplete-light which loads some select2 stuff and this, which also seems to load some select2 javascript stuff. When I use both in the same admin, I now get a new error inside the console in firefox coming from django-autocomplete-light and the ModelSelect2Multiple widget fails to initialize completely leaving me with a widget that is not usable. If I downgrade django-nested-inline to 0.4.5, it works however. any Idea on how I might fix this? :)
