when i create objects in admin page, it is not posted to server that is selection of ModelMultipleChoiceField with FilteredSelectMultiple widget

[Byoungjun Chung]

I customized form for UserCreate and UserChange based on UserCreationForm and UserAdminForm

because My User Model have a many-to-many field.

for the field, I use a ModelMultipleChoiceField with FilteredSelectMultiple widget.

I works fine for view and change about already created user.

but, when i create new user with the field, selection is not saved.

I cannot find a solution about this with googling.

finally, i found this is a bug after 4.1 version

when i change django version to 4.0.8, it work normally.

this can be reproduced in django default user group creating with several permission.

4.1, permission is not saved.

4.0.8, permission is saved.

This looks like a duplicate of #33893, fixed in Django 4.1.1. If you're using that version or later, be sure that an old version of admin/js/change_form.js isn't cached by your browser.
