Flex Mobile，从SpinnerList获取价值数据

Question

当我使用第一个代码时它起作用，将值返回给我。但是，如果我改变

list =＆＃34; {new ArrayList（[＆＃39; test1＆＃39;，＆＃39; test2＆＃39;]）}＆＃34;

到

list =＆＃34; {Operation1Result2.lastResult}

返回值就像[object songvoting]

一样

protected function spinnerList_changeHandler(event:IndexChangeEvent):void
        {               
            Debug.text  = event.currentTarget.selectedItem;
        }

<s:SpinnerListContainer includeIn="vote" x="10" y="100" width="640" height="446">
    <s:SpinnerList id="spinnerList" width="636" height="443"
                   creationComplete="spinnerList_creationCompleteHandler(event)"
                   labelField="song" selectedIndex="1" textAlign="center"
                   change="spinnerList_changeHandler(event)">                   
        <s:AsyncListView list="{new ArrayList(['test1','test2'])}"/>            
    </s:SpinnerList>
</s:SpinnerListContainer>

Answer 1

“Operation1Result2.lastResult”的价值是多少？对我来说，这看起来像一个对象而不像IList。
