Jasper reports iReport-尝试根据至少有一个值为1的另一个组对组进行计数

jasper-reports

Jasper reports iReport-尝试根据至少有一个值为1的另一个组对组进行计数,jasper-reports,ireport,Jasper Reports,Ireport,我正在尝试使用以下信息计算报表的值：主题组有多个事件组，每个事件都有一个值为1或0的字段。我试图找出如何计算至少有一个值为1的事件组的主题组的数量我曾尝试将其拆分为多个变量，但似乎无法正确计算或重置。我可以返回所有事件的计数以及所有值为1的事件的总和我的数据显示值为1的5个事件，但我需要返回4个主题的数量。任何帮助都将不胜感激。试试这个-这是两个组和一个详细值。我们获取内部组中细节值的总和，然后对该内部组的总和大于0的值进行计数。将其放入iReport时，请查看重置类型/组和增量类型/组。
