Jasper子报表未显示

Question

我创建了一个非常简单的子报告“ dummy_subreport.jrxml”，该报告将打印静态文本。dummy_subreport.jasper包含在报告“ Calling_report.jrxml”中，该报告还会打印静态文本并包含子报告。

但是，在调用主报表时，子报表没有显示。

子报告代码为

<?xml version="1.0" encoding="UTF-8"?>
<!-- Created with Jaspersoft Studio version 6.12.2.final using JasperReports Library version 6.12.2-                                      75c5e90a222ab406e416cbf590a5397028a52de3  -->

非常感谢这方面的任何帮助。
