我有与textInput一个列表作为的itemRenderer。最初，列表装入从数据提供数据。但是，由于该项目在textInputs渲染，我必须要改变一个特定项目的价值的能力。

I have a List with textInput as itemrenderer. Initially the list is loaded with data from a data provider. However since the items are rendered in textInputs, I have the ability to change the value of a particular item.

但是，试图访问使用了以下功能更改项的值时，我仍然使用旧的价值在我的跟踪：

But when trying to access the value of the changed item using the function below, I still get the old value in my trace:

private function addItem(event:Event):void {
    trace(myDataProvider.getItemAt(myList.selectedIndex).label);
}

有人可以告诉我，我需要做的新值可用。我的itemRenderer如下图所示：

can someone tell me what I need to do for the new value to be available. My itemrenderer is shown below:

<?xml version="1.0" encoding="utf-8"?>
<s:ItemRenderer xmlns:fx="http://ns.adobe.com/mxml/2009" 
                xmlns:s="library://ns.adobe.com/flex/spark" 
                xmlns:mx="library://ns.adobe.com/flex/mx" 
                xmlns:components="components.*"
                >
<s:layout> 
    <s:HorizontalLayout/> 
</s:layout> 

<fx:Script>
    <![CDATA[


        override public function set data( value:Object ) : void {
            super.data = value;
        }

        protected function myTextInput_enterHandler(event:FlexEvent):void
        {

            trace(myTextInput.text);
                            What Next??


        }

</fx:Script>

<components:myComp1 text="{data.label}" id="myTextInput" enter="myTextInput_enterHandler(event)"/>
</s:ItemRenderer>

推荐答案

尝试使用：

<?xml version="1.0" encoding="utf-8"?>
<s:ItemRenderer xmlns:fx="http://ns.adobe.com/mxml/2009" 
                xmlns:s="library://ns.adobe.com/flex/spark" 
                xmlns:mx="library://ns.adobe.com/flex/mx" 
                xmlns:components="components.*"
                >
<s:layout> 
    <s:HorizontalLayout/> 
</s:layout> 

<fx:Script>
    <![CDATA[


        override public function set data( value:Object ) : void {
            super.data = value;
        }

        protected function myTextInput_enterHandler(event:FlexEvent):void
        {
            trace(myTextInput.text);
            data.label = myTextInput.text;
        }

</fx:Script>

<components:myComp1 text="{data.label}" id="myTextInput" enter="myTextInput_enterHandler(event)"/>
</s:ItemRenderer>
