Multiple required fields from bulk edit form are not displayed. The labels for that fields appear on form but the textboxes don't appear. I think this happens because we have scripts that run for that fields. I tried to edit customizations.xml and to put BehaviorInBulkEditForm = "Enabled" but it is not working. Is there another way to enable javascript?
I would recommend to stay away from unsupported customizations which will eventually break in future updates.
If it’s worth, then move all the logic to post-update or pre-update plugins which is fail proof server side implementation rather than client side js route.
