I have created a report table. I have set it to display 5 rows of data per page. The problem now is when there are less than 5 rows of data the table will not appear.

    Sorry that I couldn't reply earlier, as I'd a busy day at work. After looking at your report design, I found that 'Page Break' functionality is not something that you really need. I just changed the Group Expression for the group that you have, to : $F{PARENT_NAME} + (($V{REPORT_COUNT} % 5 == 0) ? "1" : "2") and set the 'Start on new page' parameter to true. Also, I changed the Chart data. Check the below jrxml data:

    What you can do is to create a dummy group with 'minHeightToStartNewPage' property set to something like 700/800 (depends on your report design) for 'portrait' and 500/550 (depends on your report design) for 'Landscape' setup. You can then set the value of printWhenExpression for this dummy group as '$V{REPORT_COUNT} % 5 == 0'.

    NOTE: If the value of minHeightToStartNewPage is not set correctly (more than the length of page), it can run into infinite loop problems.
