I've put together the design for something similar and am waiting for project go-ahead at work to implement it. The design takes a different tack.

• There is a set of authorities which define every action a given user can take.
• Each user has a given set of authorities assigned to them.
• There is a given set of menu items which are all the items that can be put into a menu.
• Each menu item knows what authority(s) are necessary to have it displayed.
• A controller will have every menu item query the user object for its specific authority(s). The menu item determines if it should be displayed.

So, when you create a new menu item, you have it (and only it) know which authority combination is required for it to be displayable. If you don't want a menu item to be shown, you simply have the controller not put it in the list for querying.

Simple.

Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!

Titles consisting of a single word are discouraged, and in most cases are disallowed outright.

Read Where should I post X? if you're not absolutely sure you're posting in the right place.

Please read these before you post! —
