我尝试运行代码时出现以下错误。

TypeError：错误＃1010：术语未定义且没有属性。

    private function calculateFIX001Value(custfields:Array):Number
    {
        var result:Number = new Number;
        var valueObj:Object;

        try{

        } catch(e:Error) {
            Alert.show(e.toString());
        }

        return result;
    }

Answer 1

TypeError：错误＃1010也称为“空指针异常”，这意味着您尝试访问空对象属性。

如果你看一下堆栈跟踪告诉你的那一行，你可能会找到没有太大问题的原因。

Answer 2

这是一个帮助您解决问题的间接答案:(因为代码中有很多东西可能是null或未定义并导致此错误）

你几乎所有的代码都在try/catch中，所以你的错误实际上并没有被抛出，你只是在追踪被捕获的错误。

抛出错误（通过删除try / catch或在catch块中手动抛出它）：

catch(e:Error) {
    Alert.show(e.toString()); //instead of this, for debugging, do the line below:
    Throw e; //this will throw the error, so you will get your stack trace and the line number of error
}

要获取错误的行号并查看堆栈跟踪，您需要在调试播放器或IDE（例如Flash或FlashBuilder）中运行。
