18 | * Implementation of {@link IPropertySelectionModel} that allows one String from | |

20 | * | |
21 | * <p>Uses a simple index number as the value (used to represent the selected String). | |
22 | * This assumes that the possible values for the Strings will remain constant between | |
23 | * request cycles. | |
