为什么子报表不拆分？答案

【问题标题】：Why does subreport not split?为什么子报表不拆分？
【发布时间】：2016-04-24 23:37:51
【问题描述】：

我正在使用 iReport 4.7.1，我有一个带有 2 个子报表的主报表（一个在标题带，另一个在细节带）。

第二个子报表比第一页长，所以我想把它拆分，以便在下一页有一部分文本。我设置：

每个波段 splitType = "stretch";
所有子报表组件都需要 Position Type=Fix Relative to Top；
子报表的每个组件 Stretch Type=No stretch;
所有子报告 Ignore pagination=false;

问题是子报表总是在下一页打印，所有报表都可以填满整个页面。我还尝试了这些属性的许多其他组合，但均未成功。

【问题讨论】：

我找到了一个可能的解决方案。我创建了多个细节带，第一个太长了。

标签： jasper-reports

【解决方案1】：

您的问题是子报表中的详细信息带有 height="701"，这意味着它将从有此空间可用的第一页开始。

老实说，我不明白您为什么将这些子报表与空数据源一起使用，试图获得固定的页面布局（如果您有子数据源，它们才有意义）。

您可能应该恢复为仅使用主报告，您可以在其中使用标题栏、详细信息栏、摘要栏和组栏创建固定页面布局。

【讨论】：

谢谢，我们倾向于使用子报表以便在不同的报表中重复使用它们。无论如何，我尝试了您的建议，但遇到了同样的问题。我应该在详细信息带中还是在组标题中发布文本？
尝试为子报表详细信息区域设置 splitType="Immediate"。
