We have the same situation. With using JpaPermission Store, when @Restrict the method or page with s:hasPermission('brandHome','update',brandHome.instace), each time seam queries the database to see if the granted role or user has that permission. As syed said , it would make lots of trancastion foreach user to check permission store.
Any solutions for that ?
I still blocked with the same problem.
Have you found any solution for that?
