I'm implementing a similar approach like you and am simply using a custom base class for my links which need to be visible by some criteria only. In this base class you can take a missing user object because of no session into account at exactly one place. Your role as the only deciding criteria for visibility or not could easily be propagated using a CTOR or such. Additionally, you should not override isVisible, but onConfigure instead and call setVisible as needed.
