Javascript containing List<> - can not make them work in WebPlayer

I made some scripts with Lists. They work in Editor, but I could not make them work in the WebPlayer.
Then I added

import System.Collections.Generic;

statement in all the scripts using Lists, but that did not help. They still work in the Editor and not in the Webplayer. Any suggestions, please!

In javascrit(actually unityscipt, but i always hated ppl criticizing me :P) you would add a period before the first carrot

var palettes:List.<List.<Object> > = new List.<List.<Object> >();

My example is a 2D List which can be turned into a jagged list of any type in javascript(unityscript)

for c#

var palettes = new List<List<object> >(); //allows for all system types

Maybe the problem is you never construct them? Impossible to tell w/o code, so far so good i guess except the inner List portion, which is a big deal… You must specify the occupying type, easiest being Object (object in C#). This allows for any type of variable to be place into the list.
