Inline forms not working after django 4.1

[guilleijo]

• Django better admin ArrayField version: 1.4.2
• Django version: 4.1.4
• Python version: 3.11
• Operating System: macOS 12.6 (Monterey)

Description

When using a better array field in an inline admin the Add another button does not work on new items. The Uncaught TypeError: Cannot read properties of undefined (reading '0') error is seen in the console when adding a new inline item.

This is caused by changes in django 4.1. From the docs:

Changed in Django 4.1:
In older versions, the event was a jQuery event with $row and formsetName parameters.
It is now a JavaScript CustomEvent with parameters set in event.detail.

Possibly related to some of the issues people are having described in issue #25

in my case adding extra = 1 (or 2... not zero) to TabularInline class solved the issue. when the value of extra is zero issue comes back

that solution works only for the first new item. if you will add another one - button won't work

I created a PR with the fix here, but I don't think that it will be merged. Sadly, looks like this is not maintained anymore.
