As a really big stab in the dark, how about : | <page view-id="/showSpace.xhtml"> | <restrict>#{not selectedSpaceInstance = null}</restrict> | </page> | I'm not even sure if this is the correct syntax, but I'm sure you get the idea. If this doesn't work, you could always have a bean method called hasSelectedSpaceInstance which checks if the seam var is null View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4052712#...
