Hi, I created a custom field in database structure -> models for the purchase.order, of type many2one, with relation to res.partner. I added that field on the form view for the purchase order, using <field name="x_partner_contact" domain="[('parent_id','=',partner_id)]"/>.
It shows up poperly, the domain filter works accordingly, but when I save the purchase order, this field remains blank/unchanged. It only saves it the very first time I create a purchase order then if I try to edit it later it doesn't change when I save the order, it reverts to the first value I saved initially. The field is not readonly, and doesn't have any other atributes except the domain. Using oddo 7.
I don't understand why that happens, I've added many2one fields like this before and it worked normally. Even on the purchase order I've added other custom fields (text) and those are saved normally. Is there something else I must do/check? Can someone help me?
Thank you
