We are using Perspectives with visual personalization in some of our projects. We just started using OLS with these models as well. Currently we have one secured table that only 1 user role should be able to see and access. We have hidden this table for all other roles. However we include this table in all Perspectives so the users in the 1 role can slicer their data using this table. The table appears as an option for all users regardless of their role, but only provides data to the users in the 1 role that has access. I would think that Perspectives should honor the OLS rules and hide the table in the Persective for users who do not have access.
