将xls决策表转换为BRMS工作台中的决策表时出错

Question

我在StackOverflow上发现了类似的问题，但没有答案：Error converting xls decision table to guided decision table BRMS

我的xls文件是这样的：

将其作为决策表（电子表格）上传后，表格“验证”可以提供正确的来源（当时阻止时正确）但当我尝试将表“转换”为引导决策表时会生成* .gsdt决策表，我在服务器控制台上收到以下错误：

请参阅以下工作台屏幕截图以供参考：

注意：上传xls文件后，上传决策表的源部分会正确显示规则但是一旦我尝试转换它，规则就会丢失部分代码。

任何可以指导我正确方向的想法都将受到赞赏。提前谢谢！

这是一个截至目前的错误。我直接与几位红帽人谈过，这些可能会在未来的版本中修复。我很快就会提出功能请求。
