I'd like to have a tree view of issues selected by a domain [('message_follower_ids','in ', uid)] where uid is the logged in user. However, the Uid is related to the user id integer and what is needed here is the uid.partner_id. This is unavailable from here as far as I can see.

Is there an easy way to do this? An answer to another similar question says it can be done with a record rule [('message_follower_ids','in', user.partner_id.id)] but I don't want to restrict the records to a group in this way.
