I'm trying to get a subreport working for a report using an XML document as a data source. When I'm sorting main report data, subreport won't have to requery the XML document. Its expecting a JRSortableDataSource, not a JRXmlDataSource.What am I doing wrong? I used following datasource expression: $P{REPORT_DATA_SOURCE}).subDataSource("/B/C") Error filling print... Error evaluating expression : Source text : $P{REPORT_DATA_SOURCE}.subDataSource("/person/phone") net.sf.jasperreports.engine.fill.JRExpressionEvalException: Error evaluating expression : Source text : $P{REPORT_DATA_SOURCE}.subDataSource("/person/phone") at net.sf.jasperreports.engine.fill.JREvaluator.evaluate(JREvaluator.java:203) at net.sf.jasperreports.engine.fill.JRCalculator.evaluate(JRCalculator.java:591) at net.sf.jasperreports.engine.fill.JRCalculator.evaluate(JRCalculator.java:559) at net.sf.jasperreports.engine.fill.JRFillElement.evaluateExpression(JRFillElement.java:966) at net.sf.jasperreports.engine.fill.JRFillSubreport.evaluateSubreport(JRFillSubreport.java:384) at net.sf.jasperreports.engine.fill.JRFillSubreport.evaluate(JRFillSubreport.java:286) at net.sf.jasperreports.engine.fill.JRFillElementContainer.evaluate(JRFillElementContainer.java:259) at net.sf.jasperreports.engine.fill.JRFillBand.evaluate(JRFillBand.java:459) at net.sf.jasperreports.engine.fill.JRVerticalFiller.fillColumnBand(JRVerticalFiller.java:2044) at net.sf.jasperreports.engine.fill.JRVerticalFiller.fillDetail(JRVerticalFiller.java:778) at net.sf.jasperreports.engine.fill.JRVerticalFiller.fillReportStart(JRVerticalFiller.java:288) at net.sf.jasperreports.engine.fill.JRVerticalFiller.fillReport(JRVerticalFiller.java:151) at net.sf.jasperreports.engine.fill.JRBaseFiller.fill(JRBaseFiller.java:909) at net.sf.jasperreports.engine.fill.JRFiller.fill(JRFiller.java:126) at net.sf.jasperreports.engine.JasperFillManager.fill(JasperFillManager.java:464) at net.sf.jasperreports.engine.JasperFillManager.fill(JasperFillManager.java:300) at net.sf.jasperreports.engine.JasperFillManager.fillReport(JasperFillManager.java:757) at com.jaspersoft.ireport.designer.compiler.IReportCompiler.run(IReportCompiler.java:1003) at org.openide.util.RequestProcessor$Task.run(RequestProcessor.java:572) at org.openide.util.RequestProcessor$Processor.run(RequestProcessor.java:997) Caused by: groovy.lang.MissingMethodException: No signature of method: net.sf.jasperreports.engine.fill.SortedDataSource.subDataSource() is applicable for argument types: (java.lang.String) values: [/person/phone] at org.codehaus.groovy.runtime.ScriptBytecodeAdapter.unwrap(ScriptBytecodeAdapter.java:54) at org.codehaus.groovy.runtime.callsite.PojoMetaClassSite.call(PojoMetaClassSite.java:46) at org.codehaus.groovy.runtime.callsite.CallSiteArray.defaultCall(CallSiteArray.java:40) at org.codehaus.groovy.runtime.callsite.AbstractCallSite.call(AbstractCallSite.java:116) at org.codehaus.groovy.runtime.callsite.AbstractCallSite.call(AbstractCallSite.java:124) at TestParam_1362739351228_895383.evaluate(calculator_TestParam_1362739351228_895383:223) at net.sf.jasperreports.engine.fill.JREvaluator.evaluate(JREvaluator.java:190) ... 19 more
