---------------------------------

    Resolution: Not A Problem
      Assignee: Mark Kessler

Tested with below app.  This is not a bug.  

Change event:  Dispatched when the selectedIndex or selectedItem property changes as a result
of user interaction.
http://flex.apache.org/asdoc/mx/controls/listClasses/ListBase.html#event:change

valueCommit: Dispatched when values are changed programmatically or by user interaction.
