[xwiki-devs] XE trunk+Admin App: why is "register" still possible even if forbidden for unregistered users?

Hello, I have installed last Admin App and I had to reconfigure some rights. I go in the "Rights" menu in xwiki admin and "Users" and I forbid "Register" for "Unregistered Users"... But when I go back to the home page, I still can see "Register" and I can register. Do you any clue about this? Pascal
