Przemyslaw Jaskierski commented on JBSEAM-3749:


I've tried with restrict but it wasn't suitable solution. But maybe I'm missing something. I think that you mean something like this (pseudo code):

<page view-id="x">
    <restrict>#{identity.loggedIn or mySessionScopedCookieVerifier.hasUserOurCookieSet}</restrict>

But AFAIK this would not solve the test case. If user is not logged in and our cookie is not set he gets AuthorizationException(AccessDeniedException?) from <restrict/> and gets redirected to "Not enough privileges" error page - instead of being gracefully redirected to login page to fulfill the identity.loggedIn condition. Putting this check in login-required would fix this gracefully IMHO. Of course I can miss something here, it's your code :)

> There is a lot of scenarios which are impossible to accomplish without EL support in login-required attribute. Example: some pages should be freely accessed by recognized users (users who have e.g. you cookie set in it), but require login or registration from unrecognized users. Conditional check against e.g. session-scoped bean in login-required would be clean an elegant way to achieve this. Ok, you can add several intermediate views and redirect amongst them to achieve this, but it looks ridiculous comparing to clean EL approach.
