Hi Bastian Two suggestions that might help 1) In ognl you don't necesarily need to ask if something is null using "==null" you can use "ognl:!user" http://www.ognl.org/2.6.9/Documentation/html/LanguageGuide/coercion.html
"ognl:!user or (!user.hasPermission(@theClass.THE_PERMISSION))" 2) Given that it's a classic !A OR !B, flip it applying De Morgan's "ognl:!(user and user.hasPermission(@theClass.THE_PERMISSION)))" You can try them just to see if you get the same results.
