In the code-based reality we live in, this would raise an exception. It wouldn't be an AccessDeniedException, it'd be NullPointerException or something, because there's a problem actually asking the guard the question. So you still don't need a confirmation, because both "bad" scenarios will raise exceptions. If that happens, you'll have to check the exceptions to tell whether the user isn't allowed, or if there's just simply a problem with checking whether they're allowed, but structured exception handling makes that a snap. Which isn't to say that I want to argue the point, but rather that object systems have some fundementally different rules than real life, and they have to be taken into account. cheers, barneyb -- Barney Boisvert [EMAIL PROTECTED] 360.319.6145 http://www.barneyb.com/ Got Gmail?
