How to connect branch company res.company

[lekiend]

I see in your configuration page that I can set a company ID (res.company).
I work with Branches (to separate different websites activities).

I can not save anything else <> 0. If I enter another number, and save, it come back to 0

Thank you

company_id is not stored in options "wp4odoo_connection".
I guess this variable is not stored when you save the option
