使用XML源时Jasper Report列表为空

我目前正试图在JasperReports中第一次使用列表组件，并且发现有困难。使用XML源时Jasper Report列表为空

在JR Studio中，我正确地配置了列表并设法在预览中显示它;但是，在Java中使用报告时，我会正确地为其提供JRXmlDataSource（因为它在报告中显示数据），但它不会到达显示0行的列表组件。

我试过和不工作：

薪火XML_DATA_DOCUMENT参数（这是它如何工作的JR工作室，没有这样的运气之外吧内），或XML_INPUT_STREAM一个，或任意数量的所述XML_默认参数
在参数存放JRXmlDataSource并将它传递给所述列表作为REPORT_DATA_SOURCE
传递上述JRXmlDataSource -in-A-参数作为<dataSourceExpression>
更改列表中的文本字段的评估时间Auto，或检查Print when Overflow箱

什么工作：

喂养列表中的空数据源（所以我知道它可以实际上显示我想要的东西）

我在这里淹没;到目前为止，我所做的任何搜索都没有找到对我有用的东西。有什么我失踪？

这里是.jrxml文件（简体）：

我设法弄清楚我丢失的东西 - 在上调用我正在通过。 REPORT_DATA_SOURCE以这种方式无法使用，因为它已经变成不可用的SortedDataSource，并且在从自定义参数中引入它时，我忘记了这一额外步骤。
