   * This is a dummy class to fix the Rice 2.2 M4 issue... when we use finalizeMethodToCall() with
   * Multi select controls, it results in NPE. To fix the NPE (KSENROLL-3423), created this dummy
   * values finder which would return a single element. This has been already fixed at the rice
   * trunk. So, the rice upgrade should fix this issue..
