I haven't used the ListView much, but I think the following patch will work. 
All you needed to do was add a column for the data and then do "some stuff" 
in the Data function...  If the patch doesn't work for you, I can send the 
altered file.  Note: ignore my variable names, etc, 'cause I just hacked 
until it worked ;o)
