带有手动标记的 pdf 报告抛出 EmptyStackException
The pdf report with manual tagging throws EmptyStackException
我有 spring webapp，我在其中使用 JasperReports 生成一些基本的数据库查询报告并导出为 pdf。
我已经尝试以编程方式添加标签而不是使用 jrxml，使用 dynamic-jasper 并且遇到了不同的问题。我的 jrxml 文件几乎是 Jaspersoft Studio 中 tabular-report.jrxml 示例的副本。如果您需要查看其他内容来解决这个问题，请告诉我，此时任何帮助都将不胜感激。

这是我的 jrxml 文件：

This works, deleted because its sensitive.

错误是由 net.sf.jasperreports.export.pdf.tag.table=end 属性 引起的，它是在您报告的详细信息区域中的一个元素上设置的。查询结果中的每条记录都会重复详细信息带，因此在详细信息带中设置 net.sf.jasperreports.export.pdf.tag.table=end 没有意义。
属性 应设置在仅在 table/page 末尾打印一次的元素上，例如在页脚区域中：
<pageFooter>
<band height="1">
