I've added a new field to the res.partner model. This field dummy is a many2many, related to a customized model named res.partner.link.category. In the tree view of partners, if I click on search and then on advanced search, I can create a new filter, selecting a field from res.partner and setting its value/s.
The problem is that I can't see my new field in the advanced search. There's an existing many2many field in res.partner, named category_id, and I can see this one there, in the advanced search. I need my field to behave like that one.
Can anyone help me, please?
