Yes, but this means people have to explicitly write class="java.util.ArrayList" if they don't want to use preinstantiated instance. All they really want is to write (list)...elements(/list). I leave the preinstantiated attribute - false by default. I think it is simple enough. What we really wanted is to have Juha's case resolved. ;-) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4060444#...
