I checked the rule for

Project/Task: portal users: public or portal and following

['|', ('project_id.privacy_visibility', '=', 'public'), '&', ('project_id.privacy_visibility', 'in', ['portal', 'followers']), '|', ('message_follower_ids','in', [user.partner_id.id]), ('user_id', '=', user.id), ]

Group

Portal

There are 2 menu sections:

Tasks (here anyone can sell every task even though he is not a project follower, and and the project is not visible) My task (only his employee task)

Can u explain to me that rule ?

All of my project are set on visibility: followers only. I don't know why employees that are not followers can see all the tasks.

Thanks.
