Problem splitting subreport

[manuatilomb]

I have a report with 4 sub-reports in 4 different Details, with the last one spawing several pages, or none, depending of the amount of results and if they fit in the page or not. I want it to break into a new page in case it doesn't fit completely in the page it is, but I haven't had any good results yet. I've tried using different configurations of split, stretch, alignments, etc, that I've found searching through similar problems, but I can't reach a solution. Any suggestion would be completely appreciated (I'm using iReport 5.6.0, for more info).

Here's an example. "Top Sellers" is part of the sub-report, but it starts printing at the end of the page, where it finds space, instead of breaking into a new page.

Did you try setting Split Type property of  Detail band to "Prevent". This would keep the elements to gether for the first time when there is a split

I tried it, but I get an error when executing the code: net.sf.jasperreports.engine.JRException: The subreport is placed on a non-splitting band, but it does not have a rewindable data source.

 

I'm looking now at some solution more on the code side (I use Java to load the data on the report), but I still need some help figuring this out.

Solved: I was using a JRDataSource instead of a JRRewindableDataSource in my code. Once I changed it, and setted the Split Type property of the Detail bands to "Prevent" (as AnnMary Thomas suggested), it worked just fine
