How to introduce the page break after pre-defined number of rows in the jr:table component?
I am using jasper report version 6.1 and wanted page break after pre-defined number of rows in the jr:table component. I have also tried doing the same in version 5 and it works fine but in version 6+ I am not able to do it.
Sharing the links which I followed if any one have other solution please let me know.
This is what I have tried:

Solution
The solution to use a a group expression inside the subdatset works perfectly fine also in jasper reports v6+.
Example (built from code and data from this answer)
Adding groupExpression to the subDataset to break to new page every 2 records ($V{REPORT_COUNT}-1)/2)
<subDataset name="tableDataset" uuid="7a53770f-0350-4a73-bfc1-48a5f6386594">
<field name="User" class="java.lang.String"/>
<field name="Rep" class="java.math.BigDecimal"/>
<group name="pageBreakGroup" isStartNewPage="true">
<groupExpression><![CDATA[(int)(($V{REPORT_COUNT}-1)/2)]]></groupExpression>
</group>
</subDataset>
