fitnesse slim java.lang.ClassCastException：java.util.ArrayList无法强制转换为java.lang.String

Question

我正在与fitnesse合作。虽然我以前曾在Fitnesse维护工作，但这是我第一次实施它。

一切似乎都已到位，但是当我执行测试时，我在我的wiki页面上得到了以下异常。

在调查中，我看到该程序退出以下步骤：

执行退出此调试语句

根据需要正确检索数据。我在这里使用Query表来比较我的数据。将所有值插入到嵌套列表中，直到我达到fitnesse wiki apage上每个单元格中所需的奇异值。此方法中的消息变量具有以下异常：

Answer 1

在进一步分析中，我意识到问题是由于超出了结果的长度。

要传递给OutputStream.write（）方法的参数的长度不应超过BufferedOutputStream.buf变量的长度。如果确实如此，程序将退出，显示Fitnesse Wiki页面上的ClassCastException。
