当细带将“拆分类型”用作“阻止”时，JasperReport获取NullPointerException

时间：2018-09-24 06:28:56

标签： nullpointerexception jasper-reports

环境：

  • Jboss 5.2
  • Javaee 6
  • JasperReport 6.5.1

当我在明细栏中使用Split Type = Prevent时，在JasperReport类中出现NullPointerError，但是当我使用Split Type = NULL时，效果很好。

报告 

...

这是JasperReport 6.5.1版中的错误-请参见https://community.jaspersoft.com/jasperreports-library/issues/10486和https://community.jaspersoft.com/jasperreports-library/issues/10761

您可以在6.6.x版上升级JasperReports，也可以通过在 jasperreports.properties 中设置以下属性来避免该错误的方法：

net.sf.jasperreports.legacy.band.evaluation.enabled=true
