Two Interdependent select2 fields reset each other?

[MiroJelev]

Goal
I want to make filters for a table that inter depend on each other so that it doesn't matter which filter I choose to start with first.

Problem
The problem comes when I set the filters to depend on each other in the dependent_fields like so:
https://django-select2.readthedocs.io/en/latest/extra.html#interdependent-select2
When I select the first field, everything is okay, but when I click a new value for the second field, it resets (clears) the first field. The same happens when I try the other way around.
Am I missing something?

Cheers!

Code Snippet

class Test1Widget(s2forms.ModelSelect2Widget):
    search_fields = [
        "code__icontains"
    ]
    dependent_fields = {
        "test2": "db__test2",
    }

class Test2Widget(s2forms.ModelSelect2Widget):
    search_fields = [
        "id__icontains"
    ]
    dependent_fields={
        "test1": "db__test1",
    }
test1 = ModelChoiceFilter(queryset=test1.objects.all(), widget=Test1Widget)
test2 = ModelChoiceFilter(queryset=test2.objects.all(), widget=Test2Widget)

Hi @MiroJelev,

Thank you for reaching out. Honestly, I haven't considered this use case yet. Interdependent fields are not sound like they are going to introduce a lot of trouble, on a database level or using select2.

Would you mind sharing the exact use case? Every so often, the best solution isn't to add a patch, but to rethink the implementation. In a "the best part is no part" kinda way.

If you want to drop the clearing behavior, please you can provide your custom JS copy, while dropping the val('') in this line

django-select2/django_select2/static/django_select2/django_select2.js

Line 63 in 5753384

$(this).val('').trigger('change')

Cheers!
Joe
