Autocomplete fields and cleaned_data

[Melvyn Sopacua | 3YOURMIND]

I'm currently looking at a bug in our application, caused by autocomplete_fields on a ModelAdmin. It seemingly removes the field from self.cleaned_data, which means we can no longer validate it.

I can reproduce this by removing/adding the field from/to autocomplete_fields and resubmitting the form after re-rendering. This is a vanilla manytomany relation.

So now I wonder if this is an implementation bug in Django, with us (something else I'm not considering) or documentation bug, as none of this is mentioned in the documentation on either concepts.

I'm happy to file a bug report and classify it according to the above if it is a bug. Otherwise, I'll dive down the rabbit hole.

If that is the case it is a bug I'd say.
