Group Break on Odd numbered pages
2003-12-02 05:34
We have a report that is printed on double-sided paper.

The report is grouped and we don't want a new group to start on the back of a page.

Basically we want to be able to force each group to start on an new odd numbered page.

Is there a way to do this? (other than to run the report mulitple times, once for each group)

Just so I'm clear, we want a report to print like this

Page 1 - Group1
Page 2 - Group1
Page 3 - Group2
Page 4 - Group2
Page 5 - Group2
Page 6 - (blank)
Page 7 - Group3
Page 8 - (blank)
Page 9 - Group4

etc.

Would this be possbile by adding a second group footer that is large enought to force a new page, that only prints if the group ends on a odd numbered page?

Good luck!

Yes it does work.

I created a second group that has the same <breakexpression> as the original group.

This second group only has a footer, which is sized to be slightly smaller than the printable page height and a <printWhenExpression> that is:

new Boolean($V{PAGE_NUMBER}.intValue() % 2 == 1)

So this footer will try to get added only on the bottom of odd numbered pages, and since it won't fit, it gets pushed onto the next even numbered page.

This forces a blank (even numbered) page so the next group will start printing on an odd numbered page.

Note that I needed to define this new group before the original group in the XML file, or else the real footer doesn't appear in the right place.
