使用新版jor后统计图中数据集记录为空时报错.

处理中

问题已解决，请下载最新版本：

今天升级了新版本,发现这个问题依然存在,
另外,双击统计图表后弹出图表属性这个窗口是在最右边,而且无法被其它窗口覆盖?
如果我把该窗口移到中间再点击选择数据集后,弹出来的数据集选择窗口就看不到了.

关于窗口的问题，请下载chart.jar，并替换即可解决,

还有，你程序报错的问题，是否用我们的示例数据源也会出错？另外，请贴上你的报表模板文件，我们来测试一下。

在设计器里面,新建报表,
选择统计图.数据集里面直接写
select 1 次数,'统计' 统计 from dual
where 1 = 2
