Hi Guys, I am trying to write a custom ACL plugin to restrict access to individual wiki pages, it works like this: putting the tag {{restrict group=developers /restrict}} at the beginning of the wiki page. my problem is: if the access is denied, I need to change the wiki page content to display some friendly message. However I don't know how to modify the content outside my syntax scope. if I use $renderer->doc .= "access denied", it only replace my syntax but not global content. I know the builtin ACL does similar thing but I just don't know which internal function to use. Please help. Cheers James Lin
