                                In this test case, the valuePassThru attribute is set to true, therefore the value is passed through
                                to the client. If you  need to have the value on the client, one reason might be
                                if you are relying on the value for javascript, then set valuePassThru to true.
                                Otherwise, it defaults to false, and the client-side value will be an index, and converted
                                automatically on the server. valuePassThru=false allows the component to be bound to
                                custom Objects. valuePassThru=true works ok when the value is bound to Strings. "/>
