我跟着this线程尝试将子报表metrics.LINES_OF_CODE_1和metrics.MAINTAINABILITY_1中的值从子报表返回到主报表，但唯一得到的值为空。我JRXML文件中找到如下：将子报表中的值返回主报表

[从子端口到主报表的返回值为空]的可能重复（http://stackoverflow.com/questions/19384421/returned-value-from-subeport-to-main-report-is-null） – 2016-09-30 16:14:47

我通过在调用我的输出变量的字段上将评估时间从“Now”设置为“Auto”来解决这个问题。

对于人谁也改变不了的评估时间（因为他们焕的变量作为参数传递到另一个子报表的为例）：

不要使用变量returnes在同一频带比报表本人！

做作做我觉得在乐队的渲染结束...

所以-​​--->“添加另一个带”和内部使用的变量;）

希望这可以帮助，我花了几个小时发现这一点！
