[flexcoders] Tilelist itemRenderers

[guero235]

I have an odd thing happening in my tilelist.  I am using a custom 
renderer that basical is an image inside of an hbox.  For the image 
source, i am using bindable bitmap data instead of a url.  Everything 
works fine at first, but as the tilelist gets longer, the previous 
images start disappearing.  Then when i scroll up and down, they all 
disappear and are not redrawn. Any ideas?
 
Thanks,
 
John
