> "net.sf.jasperreports.engine.JRException: The subreport is placed on a
> non-splitting band, but it does not have a rewindable data source."
> The ValueStackDataSource implements JRDataSource, not JRRewindableDatasource,
> If a "non-splittable" subreport iterates over a collection that might go over
> the page boundary, an exception is thrown because it cannot rewind the
> collection.
