Hi @dimitry

Hope you are doing well.

Here in odoo 16 what happens is that in the field 'B' you have given the group and when you are trying to use this field in another field as an attribute "Field 'B' used in attrs ({'readonly': [('B', '=', True)]})" it is getting restricted due to the applied group. 

Hence you can either move the group from the field or add the same field where its is being used as attribute as invisible.


I hope it will help you.

Thanks & Regards,

Hi,

Create a group and add the attribute to the field that you want to make as read only as below.

<field name="example_field" attrs="{'readonly': [('groups', 'in', [example_group])]}"/>
