jasper-reports - iReport 4.1.3 表格组件从不显示数据集的第一个条目

标签 jasper-reports ireport xmltable

使用 ireport 表组件时，我遇到一个可能很简单的问题。我使用 XML 作为报告的数据源。

问题是该表从不显示与其关联的数据集的第一个条目。 想象一下我有这些数据:

<name>
   <first>adam 1</first>
   <last>sand 1</last>          
</name> 
<name>
   <first>adam 2</first>
   <last>sand 2</last>          
</name> 
<name>
   <first>adam 3</first>
   <last>sand 3</last>          
</name>

输出(表)将为(除第一行之外的所有数据):

第一个最后一个
亚当2沙2
亚当3沙3

表格中缺少数据源的第一行。

我认为这是与主数据源迭代相关的问题。您可以阅读
Why is the first record missing from my subreport?在 community.jaspersoft.com 上发帖。
