Hey I'm getting the following exception when I try to nest tables. My object contains as attribute a list that itself has a list of other object. I'm capable of creating a table that iterates over the first list by when I try to iterate over the sublist i get the following error: net.sf.jasperreports.engine.JRRuntimeException: java.lang.NoClassDefFoundError: report1_InterestingCaseDataSet_1277809238286_246631_InterestingCaseReasonDataSet (wrong name: report1_InterestingCaseReasonDataSet_1277809238286_246631) at net.sf.jasperreports.engine.fill.JRFillSubreport.prepare(JRFillSubreport.java:710) at net.sf.jasperreports.components.table.fill.FillTableSubreport.prepareSubreport(FillTableSubreport.java:156) at net.sf.jasperreports.components.table.fill.FillTable.prepare(FillTable.java:302) at net.sf.jasperreports.engine.fill.JRFillComponentElement.prepare(JRFillComponentElement.java:129) at net.sf.jasperreports.engine.fill.JRFillElementContainer.prepareElements(JRFillElementContainer.java:329) at net.sf.jasperreports.engine.fill.JRFillBand.fill(JRFillBand.java:419) at net.sf.jasperreports.engine.fill.JRFillBand.fill(JRFillBand.java:378) at net.sf.jasperreports.engine.fill.JRVerticalFiller.fillColumnBand(JRVerticalFiller.java:2018) at net.sf.jasperreports.engine.fill.JRVerticalFiller.fillDetail(JRVerticalFiller.java:757) at net.sf.jasperreports.engine.fill.JRVerticalFiller.fillReportStart(JRVerticalFiller.java:269) at net.sf.jasperreports.engine.fill.JRVerticalFiller.fillReport(JRVerticalFiller.java:127) at net.sf.jasperreports.engine.fill.JRBaseFiller.fill(JRBaseFiller.java:938) at net.sf.jasperreports.engine.fill.JRBaseFiller.fill(JRBaseFiller.java:860) at net.sf.jasperreports.engine.fill.JRFiller.fillReport(JRFiller.java:84) at net.sf.jasperreports.engine.JasperFillManager.fillReport(JasperFillManager.java:624) .... A part of my jrxml is attached. Does anyone have a idea, what i'm doing wrong?

I'm using Nested Java Collections to generate a report. I've managed to display a nested collection of my main objects as a table. Now I would like to display another level as a table within a table, but the engine throws an exception on this. The main java object contains a List-attribute named "interestingCases". And an InterestingCase object contains & List-attribute named "interestingCaseReasons". Can anyone tell me, if it possible to nest these tables and if so, what I'm doing wrong.
