Hi everyone! I've got a text field on page header, a text field on page footer and a crosstab on report footer. I need to print page header on first page of report and page footer on the rest pages. So I usualy use property 'print when expresson' that include next expression: '$V{PAGE_NUMBER} == 1' or '$V{PAGE_NUMBER} > 1' But after adding crosstab on template I've got next error on generating report: net.sf.jasperreports.engine.JRException: net.sf.jasperreports.engine.fill.JRExpressionEvalException: Error evaluating expression for source text: $V{PAGE_NUMBER} == 1 at com.jaspersoft.studio.editor.preview.view.control.ReportController.fillReport(ReportController.java:551) at com.jaspersoft.studio.editor.preview.view.control.ReportController.access$18(ReportController.java:526) at com.jaspersoft.studio.editor.preview.view.control.ReportController$1.run(ReportController.java:444) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:63) Caused by: net.sf.jasperreports.engine.fill.JRExpressionEvalException: Error evaluating expression for source text: $V{PAGE_NUMBER} == 1 at net.sf.jasperreports.engine.fill.JREvaluator.handleEvaluationException(JREvaluator.java:294) at net.sf.jasperreports.engine.fill.JREvaluator.evaluate(JREvaluator.java:328) at net.sf.jasperreports.engine.fill.JRCalculator.evaluate(JRCalculator.java:673) at net.sf.jasperreports.engine.fill.JRCalculator.evaluate(JRCalculator.java:641) at net.sf.jasperreports.engine.fill.JRFillDataset.evaluateExpression(JRFillDataset.java:2028) at net.sf.jasperreports.engine.fill.BaseReportFiller.evaluateExpression(BaseReportFiller.java:704) at net.sf.jasperreports.engine.fill.JRFillBand.evaluatePrintWhenExpression(JRFillBand.java:357) at net.sf.jasperreports.engine.fill.JRVerticalFiller.fillPageHeader(JRVerticalFiller.java:401) at net.sf.jasperreports.engine.fill.JRVerticalFiller.fillReportStart(JRVerticalFiller.java:260) at net.sf.jasperreports.engine.fill.JRVerticalFiller.fillReport(JRVerticalFiller.java:110) at net.sf.jasperreports.engine.fill.JRBaseFiller.fill(JRBaseFiller.java:621) at net.sf.jasperreports.engine.fill.BaseFillHandle$ReportFill.run(BaseFillHandle.java:135) at java.lang.Thread.run(Thread.java:748) Caused by: java.lang.UnsupportedOperationException at net.sf.jasperreports.compilers.DirectEvaluator.evaluate(DirectEvaluator.java:50) at net.sf.jasperreports.engine.fill.JREvaluator.evaluate(JREvaluator.java:313) ... 11 more What I have to do to solve this problem? P.S. if use only boolean value on band or text field then report will be generate correct
