I got a view, which lists nodes of same type, a "Other activities" view, i use this view on a activity node view. However i don't want the node i am currently viewing, to show in the list as well.
So what i did, was to make a contextual filter for nid, and provide a default value of "Content ID of URL", of course now my list only provides me with the currently viewing node.
Isn't there anyway to negate this? So it shows all other nodes, that don't have the nid, og the current?
