iReport 4.1.3 表格组件从不显示数据集的第一个条目

【问题标题】：iReport 4.1.3 table component never shows the first entry of the datasetiReport 4.1.3 表格组件从不显示数据集的第一个条目
【发布时间】：2017-07-22 01:36:18
【问题描述】：

在使用 ireport 表格组件时，我遇到了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（表格）将是（除第一行之外的所有数据）：

先到后
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上的迭代有关的问题。您可以阅读 community.jaspersoft.com 上的
Why is the first record missing from my subreport? 帖子。

【讨论】：

  • 首先感谢您的回复。我无法从查询中删除 ZoneID，因为此报告实际上是一个子报告，它接收 ZoneID 以过滤与其关联的能量。如果我删除它，表格会显示该建筑物所有区域的所有能量（奇怪的是没有再次显示第一行）。谢谢
  • 您能发布包含更多我的信息的数据文件吗？我再试一次
  • 我只有ZoneID 的数据等于参数。这是错的吗？这是我数据文件中的前三个ActiveEnergy。
  • 是的，它适合您。你在使用表格组件吗？如果我只是将字段放在详细信息带中，它会为正确的 ZoneID 打印所有字段。我的问题是使用表格组件。
  • 是的，我已将您的 jrxml 文件与我的数据文件一起使用
