Hi, quite stupid question for such long time freemarker user :-) What is the best way to find out whether potentionally missing sequence is not empty? I used to use: (list?if_exists?size > 0) I never know whether exists operator will for empty list return true (as I expect) or not. So I use the trick with size, which is quite long to write. The documentation does not help there, so I would have to test it. I lack ?empty built-in: (list!?empty) in new syntax ..
