Unwanted Page Break before Summary Band

[kent.vickery]

I have a two-column subreport that has a header band, detail band, and summary band.  For some reason Jasper generates a page break before the summary band even though there is lots of space left on the report for the next subreport.

If I swtich to one-column OR disable printing of the summary band, then the unwanted page break goes away.  I've made sure all of the content fits within the page.

Help!

Uncheck summary on new page property and try. Thanks.

[kent.vickery]

Thanks for the feedback, but I should have said I had tried all of the obvious solutions.

With further testing I found the unwanted page break before the Summary Band only happens if there is an even number of detail records being reported in the detail band.  So, if there are either 9 or 10 detail records there are 4 rows written in the detail band (because it is a two column sub-report) - but the page break only shows up when both columns of there detail band are filled in (no matter how many rows are written).

[kent.vickery]

Sorry - I should have said either 7 or 8 detail records in my example above.

Please post your JRXML here, if possible, to help us reproduce the problem. Thank you.

Apparently there is a problem with the splitType attribute of the summary band. Try to set it as "Immediate" and see if it works as you need. If the problem is still there, please post the JRXML of the main report too. Thanks.

[kent.vickery]

Changing the splitType to "Immediate" (or any of the other options) had no effect.  When an even number of detail records are being reported in the detail band, a page break gets generated before the summary band.

Note the same problem happens when running this 'sub-report' as a stand-alone report, so the JRXML in the main report is not a factor.

At the moment the only work-around I can think of is testing the number of details records present before calling the Jasper report and generating a null/blank detail record to ensure an odd number of details are present.
