Coldfusion 数组的索引[0]无效。索引必须是正整数

以下代码在Adobe ColdFusion中工作，但由于迁移到Railo，导致以下错误：

错误消息：数组的索引[0]无效。索引必须是正整数（1，2，3，…）

联机启动时出错：local.arrChartDataResult=addPercentageData（local.arrChartDataResult）

你知道为什么会这样吗

我不认为您已经发布了相关的代码，这是基于您所说的错误发生的位置，但我强烈怀疑

addPercentageData（）

中的代码是否利用了ColdFusion按值传递数组这一事实（无论是设计还是其他）。然而，Railo通过引用传递它们，所以当您假设您只是处理函数本地数据的副本时，您可能会干扰调用代码中的数据

不过，这只是一个有根据的猜测。

Hi@Adam Cameron谢谢你的回答。它确实声明错误在我的railo错误中声明的行上。不过，我现在会用完整的错误更新我的OP:）@Adam Cameron如果有帮助的话，我还将完整的函数添加到上面的OP中。很多感谢我在Ubuntu服务器12上运行Railo 4.0.4.001 final on port:8888，我觉得

intPositionInArray

被设置为零，因为

ListFindLocase（）

找不到任何东西。你检查过了吗？错误输出是灰色的，就像AdobeCF一样，但100%是Railo4.0.4.001新安装，运行在Ubuntu上。我根本没有安装AdobeCF。我从Adobe10机器上复制了所有文件，但我不认为这有什么区别。嗨@AdamCameron谢谢你的回复。它确实声明错误在我的railo错误中声明的行上。不过，我现在会用完整的错误更新我的OP:）@Adam Cameron如果有帮助的话，我还将完整的函数添加到上面的OP中。很多感谢我在Ubuntu服务器12上运行Railo 4.0.4.001 final on port:8888，我觉得
