Question

以下是一些演示此问题的屏幕截图：首先，这里是没有列表元素的设计：

以下是该报告的结果（请注意，有两页）：

现在，如果我添加list元素，这里是设计：

以下是摘要带的jrxml：

最后这是该报告的结果。

请注意浮动＆＃34;静态文字＆＃34;标签适当地向下移动，但不足以在报告中添加额外页面。但是，您现在仍然可以看到报告中有3页。

唯一改变的是添加list元素。如何制作它以便它不会添加额外的页面？或者我对列表有什么不理解？我可能还可以将数据传递到子报告中，以便数据显示在子报告的详细信息区域中，但如果可以的话，我更愿意使用列表，因为它对我来说似乎更简单。我使用的是6.6.0版。谢谢！

这是请求的完整jrxml（删除uuids以保存字符）：

Answer 1

我以前遇到过这个问题，而我所做的修复是

检查详细区域的大小，并确保生成的值列表都可以放入同一页面。减小细节区域的大小以查看差异。
另一个是未使用或为空的皮革带。例如，尝试通过将“摘要”区域设置为“当表达式时打印”为Boolean.FALSE来隐藏该区域。
您还可以转到报告属性>选中忽略分页属性

Jasper报告列表元素产生额外的页面
