1120：访问未定义的属性[实例化变量]？ （柔性）

Question

我查看了this，this，this和this等问题，但这些问题似乎都没有描述我的问题？

我宣布这些变量：

<fx:Script>
    <![CDATA[
        import assets.Page;
        public var oneTwo:Page = new Page("...");
        public var oneThree:Page = new Page("...");
        protected var oneFour:Page = new Page("...");
        protected var oneFive:Page = new Page("...");
        protected var oneSix:Page = new Page("...");

...正在引用确实存在的对象，Flex可以使用这些项目的构造函数。接下来，我尝试设置这些对象的其他属性：

        oneThree.next = oneFour;
        oneThree.prev = oneTwo;
        oneFour.next = oneFive;
        oneFour.prev = oneThree;
        oneFive.next = oneSix;
        oneFive.prev = oneFour;

等。现在，当我单击其中的每一个时，Flex会在每个实例中突出显示变量，并在编码期间将所有变量识别为有效。但汇编给出了：

-1120: Access of undefined property oneThree.
-1120: Access of undefined property oneFour.
-1120: Access of undefined property oneFour.
-1120: Access of undefined property oneFive.

等等，每次使用一个变量（在这种情况下为十二次）。你可以看到我做了一些公开和一些保护，这似乎没有什么区别。

[这] [1]问题引导我解决问题。

第二个代码块中的变量需要在自己的函数中编辑，得到：

<fx:Script>
    <![CDATA[
        import assets.Page;
        public var oneTwo:Page = new Page("...");
        public var oneThree:Page = new Page("...");
        protected var oneFour:Page = new Page("...");
        protected var oneFive:Page = new Page("...");
        protected var oneSix:Page = new Page("...");

        oneThree.next = oneFour;
        oneThree.prev = oneTwo;
        oneFour.next = oneFive;
        oneFour.prev = oneThree;
        oneFive.next = oneSix;
        oneFive.prev = oneFour;
    ]]>
</fx:Script>

而不是：

<fx:Script>
    <![CDATA[
        import assets.Page;
        public var oneTwo:Page = new Page("...");
        public var oneThree:Page = new Page("...");
        protected var oneFour:Page = new Page("...");
        protected var oneFive:Page = new Page("...");
        protected var oneSix:Page = new Page("...");

        protected function _init():void
        {
            oneThree.next = oneFour;
            oneThree.prev = oneTwo;
            oneFour.next = oneFive;
            oneFour.prev = oneThree;
            oneFive.next = oneSix;
            oneFive.prev = oneFour;
        }
    ]]>
</fx:Script>

为我处理错误。希望这有助于其他人!!
