[flexcoders] Example: Using an item renderer with a List control

[dantmcgowan]

Hello,
    I created two files (one application file and one renderer file)
from the example (code) presented here:
   
http://livedocs.adobe.com/flex/2/docs/wwhelp/wwhimpl/js/html/wwhelp.htm?href=00000855.html
    
    It works great only I have several of these messages writing out
to the flashlog:
    
    warning: unable to bind to property 'data' on class 'Object'
(class is not an IEventDispatcher)
    
    Do you know why this is occurring and what is needed to get rid of
the warnings? Thanks,
    
 Dan
