Question

使用debian linux下的调试插件在浏览器中运行我的Flash应用程序时出现以下异常。当我使用或不使用调试器在FlashBuilder（在Windows 7下）运行应用程序时，我无法复制异常。

TypeError: Error #2007: Parameter Constructor Failed must be non-null.

我不确定这个例外意味着什么。它看起来像“参数x必须为非null”。异常，除了表明该参数被命名为“构造函数失败”，这实际上没有意义。

我认为有问题的代码在某个地方的这个块中，但是，我不知道如何让vm在堆栈跟踪中吐出行号。

// possibleInputs is a populated ArrayCollection
var sort:Sort = new Sort();
var sortField:SortField = new SortField("name");
sort.fields = [sortField];
possibleInputs.sort = sort;
possibleInputs.refresh();

Actionscript：TypeError：错误＃2007：参数构造函数失败必须为非null
