 /**
 18  
  * Implementation of {@link IPropertySelectionModel} that allows one String from
 19  
  * an array of Strings to be selected as the property.
 20  
  * <p>
 21  
  * Uses a simple index number as the value (used to represent the selected
 22  
  * String). This assumes that the possible values for the Strings will remain
 23  
  * constant between request cycles.
