[xwiki-users] stopping a page for non-editors

Hi, I'm relatively new to xwiki. I have a few pages where dynamic tables had to be shown, and I'm using PHP quite heavily there. In a couple of pages, the content is supposed to be shown only if the user is in a specific group called 'XWikiEditorsGroup'. I didn't want to rely on xwiki's native single-page permissions as they looked a little cumbersome for what I needed, and preferred to control access via the page code itself. Up to xwiki 2.7, the following velocity section, which was the first section in the page, did the trick: {{velocity}} #set($user=$xwiki.getUser()) #if(!$user.isUserInGroup("XWiki.XWikiEditorsGroup")) {{warning}}You don't have permission to view this document{{/warning}} #stop #end {{/velocity}} However, after upgrading to xwiki 3.0, this code no longer works. From what I see, the issue appears to be related to velocity 1.7 and its different syntax for the #stop directive. I can't seem to find the right syntax though. As an alternative approach, I've also tried to relocate this access control logic into the PHP code that follows the above velocity section. To do that, I need to find a way to get the true/false value of "$user.isUserInGroup("XWiki.XWikiEditorsGroup")" in PHP, but so far haven't found a way to do that either and not sure how to pass the $user object and its isUserInGroup() method to the PHP part. I've even looked into doing this in groovy but no luck there either. Any advice will be appreciated... Thanks
