As i have read in this article:
https://www.odoo.com/forum/help-1/question/multiple-attrs-in-form-86548
it should be possible to declare multiple conditional on attrs. I followed the example but the conditions :
<field name="firstname" attrs="{'invisible': [('is_company','=',True)], 'required':[('is_company', '=', 'False')]}"/>
only the invisible value is correctly set, required is not applied.
I checked the syntax, but it seems to be correct.
Do i miss something here?
( the value is_company is correctly used for the invisible value )
