Question

我目前第一次尝试在JasperReports中使用列表组件，而且我发现了困难。

在JR Studio中，我正确配置了列表并设法在预览中显示它;但是，在Java中使用报表时，我正确地将它JRXmlDataSource提供给它（因为它在报表中显示数据），但是它没有到达列表组件，它显示0行。

我尝试过但没有工作：

传递XML_DATA_DOCUMENT参数（它在JR Studio中是如何工作的，在它之外没有这样的运气），或XML_INPUT_STREAM一个，或任意数量的XML_默认参数
将JRXmlDataSource存储在参数中并将其作为REPORT_DATA_SOURCE
将上述JRXmlDataSource - 参数传递为<dataSourceExpression>
将列表中文本字段的评估时间更改为Auto，或检查Print when Overflow框

做了什么工作：

为列表提供一个空数据源（所以我知道它实际上可以显示我想要的内容）

我在这里淹没了;到目前为止，我所做的搜索都没有找到适合我的东西。我有什么遗失的吗？

这是.jrxml文件（简化）：
