[flexcoders] resizable list item

[hworke]

   Hi devs,

   I am trying to use itemrenderer in a list with
   variable height. This is how it will work: if
   the there is only one item in the list then
   the height of the item will be 100% of list height, 
   if there are 2 items then 50% height .... if 4 then 25%.

   So the height of the list item should be 
   (height of the list component)/(the length of the dataprovider).

   How can I do that?

   Regards...
