1)i'm opening a page with a button. Now i have rights to see and click it. 2)Somebody revokes my right to click this button, but I still see it because page has been opened before. 3)I'm clicking button For now page refreshes without any info (button of course isn't visible after refresh) which is misleading for user. I would like to inform user that he hasn't enough rights to click button. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4115674#...
