I'm trying to create an xls-report with JasperReports. For that I use JasperReports 5.5.0 (and iReport in the same version) and apache poi 3.9.

The base structure is a master-report with a subreport and this subreport also contains another subreport. For better understanding some code samples:

Masterreport:

The second subreport looks almost the same like the first one.

My problem is, that if the row height of the master is larger than the whole band height of a subreport, the subreport won't stretch its band height to the masters row height. I know it has to be just a simple combination of settings, but I can't find it.

正如预期的那样，它是拉伸选项的简单组合......主报告的元素不能因溢出而拉伸，但必须将属性net.sf.jasperreports.print.keep.full.text设置为true . 第一个子报表遵循相同的规则，但第二个子报表的元素必须拉伸溢出。
