Thank you, Now I changed the design using nested reports and different datasources, but still I have infinite loop problem. Take a look please Code:------level 0 report -----------------------------<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE jasperReport PUBLIC "-//JasperReports//DTD Report Design//EN"

Thank you teodord I have isSplitAllowed="true" and it does not help If I make my data source rewindable, from some reason it just enters infinite loop - I see in debugger calls to moveFirst and calls to getFieldValue and it does not stop forever.

Hi! I'm trying create a report with Jasper reports, which contains 2 subreports, working on the same data source (which is custom data source). I.e. those subreports are working on the same data. I have following "main" report jrxml (attached code snippet) and I receive exception: com.cadence.mdv.reporting.ReportingException: net.sf.jasperreports.engine.JRException: The subreport is placed on a non-splitting band, but it does not have a rewindable data source. What should I do in order to get this report working?
