Hello,  I am having trouble opening a custom form view that is restricted to a group if a user clicks a many2one field from a parent view.  For example, I have a Project Developer group that may see the partner_id field on a Project Issue form.  If the Developer clicks the partner_id field, then it should open a custom Partner form view with restricted information.  Right now it is opening the base partner form view, and shows too much information.  Does anyone know how to open a custom partner form view when clicking on a many2one, partner_id field?

I found this example here, but it isn't working for me:
