[rules-users] Slinding window !

Hi guys, While trying to understand how slinding window work, I realize that all exemples are given with "accumulate" or "collect" functions , I din't know why ?? $a : List() from collect(Event1() over window:time(2s) from entry-point "point") // work Bur why $a : Event1() over window:time(2s) from entry-point "point") doesn't work ??!
