Hello,

I am using Odoo15, and I am trying to assign the current default company to company_id field when creating a record in 'res.partner' using the following code : 

This works fine when creating a record directly from 'res.partner' model (Suppliers/ Clients menus), also when creating a new record in 'res.users' (this automatically creates a record in res.parner), the problem appears when I try creating a new company, I get the following user error : 

I guess the error occurred because I am trying to fill the company_id field in res.partner with another company_id that does not match with the new_cmpany. 

I have tried adding a condition, to separate the case of creating a company from other cases (user, supplier, client):

In the first case, keep the company_id field empty
The other cases use the assignment shown in the code, but unfortunately the condition did not work

Any suggestions please to solve this.
