Hi,
I'm trying to set up a visibility permission on content tree, basically what currently done is setup a role with none to check in content module permission, please reffer to the picture bellow for detail.
I set a test user with multiple role of which is Country Editor - Bahrain, Country Editor - United Kingdom, Country Editor - United States.
The problem is, with this setup I still can see the document in document tree.
PS. I'm not setting (not checked) any read permission for related document ie document type, or even in document level.
