How filter a field with domain with eval expression?
I've created a module where I put some new category of product that will be created by xml.
So I'have to filter some field with domain, like 'categ_it', '=', xml_id, but i try to eval=ref('xml_id') but without success.
Does anyone have some solution or exampel to suggest me?
I don't want to put normal integer id to filter fileds, I want a more generalized and dynamic option :)
