  • NPE on getting the fields from a DataSourceProvider if using crosstabs

    Assigned User Giulio Toffoli
    CategoryBug report

    If you try to write you own JRDataSourceProvider you got a NPE Reports using Crosstabs.


    From Jasper Report 3.7.1 there is a method ReportQueryDialog::jButton2ActionPerformed(java.awt.event.ActionEvent evt)


    Inside that method net.sf.jasperreports.engine.JasperReport jr = new net.sf.jasperreports.engine.JasperReport(report,"",null,null,"");

    ist called. And here is the JRExpressionCollector initialised with null!


    this variable is used inside JRBaseObjectFactory::visitCrosstab(JRCrosstab crosstab)


    here it is also null and the variable not checked to null.


    Then you got the NPE
