How to Make a Page Break at an Arbitrary Number of Lines In a Table Component

Requirement:
We are using a Table component in Jaspersoft Studio and would like to have a page break at the line that is a multiple of 20. Is this possible?

Solution:
We can achieve this requirement by creating a group and giving it an expression as below.

<group name="pageBreakGroup" isStartNewPage="true">
<groupExpression><![CDATA[(int)($V{REPORT_COUNT} - 1) / 20]]></groupExpression>
</group>

Attached pageBreakTable.jrxml report can be viewed for reference. The report can be run using the sample DB adapter in Studio.
