How to crate a dammy group that breaks on each page?

[igorns]

I tried to create dummy group that breaks on each page to be able to have footer with dynamic height on every page but my group brake does not work.

I took idea from teodord here http://community.jaspersoft.com/questions/537929/page-footer-stretching-fields, with group expression $V{PAGE_NUMBER} but no joy. There is only one group, no break on each page at all.

Any idea please?

I use the latest JapserReports 6.0.3

Thank you in advance

What Teodor said in the previous community posting is:

1) JR report page footer cannot stretch;

2) JR report group can start at a new page on group breaks;

3) JR report footer can stretch and be placed at the bottom of the page.

To meet your report requirement that needs to have variable height page footers, one approach is to utilize group footer to hold report page footer content with various text lengths. The tricky part, however, is how to trigger the group break. I am not sure how you designed your report using the group that you see no page breaks when group changes. But in general, you should not use report system variable $V{PAGE_NUMBER} for your page break because as Teodor mentioned in his comment, the group break "needs to start sooner/upper on the page", so that your group footer will have enough room to display its content on the current page without overflowing into another page. Once you reach the page break. as indicated by $V{PAGE_NUMBER} increment, it is too late to lay your group footer on the page.

There's no easy way to use group footer to achieve a dynamic report design to meet your requirement. You will need to set up some hard rules to determine how to make the group break, such as number of detail records per page, etc, and test the approach to come up with the best design solution.

Here is a demo report output using a group break with 10 records per page. Notice the group footer is placed at the bottom of the page with variable length text. The last page is the report summary band containing footer text in its entirety. The group expression used in the report is:

($V{REPORT_COUNT}.intValue()-1)/10[/code]
