Jasper报告列表元素会产生额外的页面 [英] Jasper report list element produces extra page
本文介绍了Jasper报告列表元素会产生额外的页面的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
以下是一些屏幕快照来演示该问题: 首先，这是没有列表元素的设计:
Here are some screen shots to demonstrate the problem: First, here is the design with no list element:
这是该报告的结果(请注意有两页):
And here is the result of that report (note that there are two pages):
现在，如果我添加列表元素，则设计如下:
Now if I add the list element, here is the design:
这是摘要区域的jrxml:

最后这是该报告的结果.
And finally here is the result of that report.
请注意，浮动的静态文本"标签已适当向下移动，但不足以向报表添加额外的页面.但是，您仍然会发现报告现在有3页.
Note that the floating "Static Text" label moved down appropriately, but not nearly enough to add an extra page to the report. However, you'll see that there are now 3 pages to the report anyway.
唯一改变的是添加列表元素.我如何才能使它不添加多余的页面?还是我对清单不了解?我可能还可以将数据传递到子报表中，以便将数据显示在子报表的详细信息带中，但是如果可以的话，我更希望使用列表，因为它对我来说似乎要简单得多.我正在使用6.6.0版.谢谢！
The only thing that changed was adding the list element. How can I make it so that it doesn't add the extra page? Or what am I not understanding with regard to lists? I could probably also pass the data into a sub-report so that the data is presented in the detail band of the sub-report, but I would much prefer to use a list if I could, since it seems much simpler to me. I am using version 6.6.0. Thanks!

推荐答案
我以前遇到过这个问题，而我所做的修复是.
I've encountered this before and the fixes I did was.
- 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"
这篇关于Jasper报告列表元素会产生额外的页面的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
