Ajax changing of ACL permissions for 'core' fields gives JS error, a full form save is needed to modify ACL permissions

Hello,

Joomla 3.8.6
Flexicontent 3.2.1.12
PHP 7.2.4

In the backend, in the edit page of the core Tags field, when i try to change the access right of the field to allow the registered group to modify that field from the backend, I have a javascripte error :

Uncaught TypeError: Cannot read property 'value' of null

The same issue happens to all the core fields.

Best regards.

Hello

ok so you mean

ACL permissions in field configuration
and also the field must be "Core" Type

i see the issue, the AJAX saving indeeds is not called because of JS error

if you click save on the form the ACL setting will be saved

also please note that "Edit field value" ACL is ignored for core fields

there are other setting for them either configuration or like for tags there are 2 ACL perms component configuration
