Jaspersoft Studio 6.20.0
Server 7.8.0

I have a Report with two subreports. The first one can take dynamic hight of the page.
The second one is this:

<jasperReport xmlns="http://jasperreports.sourceforge.net/jasperreports" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://jasperreports.sourceforge.net/jasperreports http://jasperreports.sourceforge.net/xsd/jasperreport.xsd" name="TEST_NOTIZEN" pageWidth="595" pageHeight="842" whenNoDataType="NoPages" columnWidth="555" leftMargin="20" rightMargin="20" topMargin="20" bottomMargin="20" uuid="110febd2-dc25-46dd-b70c-f48ad6824150">

        </band>

</jasperReport>

My goal is to fill the left space of the page, to get a grid where people can make some notes by hand, like in this Picture:

Report

To achiev this, the print when expression is set to $V{PAGE_NUMBER} == 1
This works fine and the textfields/the grid is only printed on page 1, but at the end, it always prints an additional empty page (as you can see in the image above, there’s a 2nd page which should not be there). If i put a page- or rowheader or footer these are printet on the empty page. But the additional page is also printed if there’s only the detail band.

The SQL query ist just a “pseudo” query which gives me enough rows to fill a whole page (first report can also be empty) .

I experimented for hours with all the properties but I couldn’t figure out how to get rid of that empty page.
What I have also tried is to put a Grid in de background band and set runToBottom="true". But the background is not printed if it is in a subreport…!?

Thanks in advance!
