Hi I need help... I'm making a report with ireport and netbeans calling it from a java program... all good when compiling and executing... the problem occurs when I insert a subreport... the compilation passes but when executing it gives me this mistake... Exception in thread "main" java.lang.NullPointerException at net.sf.jasperreports.engine.fill.JRPrintBand.addOffsetElements(JRPrintBand.java:101) at net.sf.jasperreports.engine.fill.JRFillElementContainer.addSubElements(JRFillElementContainer.java:623) at net.sf.jasperreports.engine.fill.JRFillElementContainer.fillElements(JRFillElementContainer.java:600) at net.sf.jasperreports.engine.fill.JRFillBand.fill(JRFillBand.java:406) at net.sf.jasperreports.engine.fill.JRFillBand.fill(JRFillBand.java:352) at net.sf.jasperreports.engine.fill.JRVerticalFiller.fillBackground(JRVerticalFiller.java:1804) at net.sf.jasperreports.engine.fill.JRVerticalFiller.fillReportStart(JRVerticalFiller.java:255) at net.sf.jasperreports.engine.fill.JRVerticalFiller.fillReport(JRVerticalFiller.java:128) at net.sf.jasperreports.engine.fill.JRBaseFiller.fill(JRBaseFiller.java:836) at net.sf.jasperreports.engine.fill.JRBaseFiller.fill(JRBaseFiller.java:765) at net.sf.jasperreports.engine.fill.JRFiller.fillReport(JRFiller.java:84) at net.sf.jasperreports.engine.JasperFillManager.fillReport(JasperFillManager.java:624) at PruebaRep.Main.main(Main.java:291)
