iReport - Problem by using conditional style

[proximus]

 

Hey,

I tried to use the first time “conditional styles” for my report and get a „field not found“ exception like:

net.sf.jasperreports.engine.design.JRValidationException: Report design not valid:

1. Field not found: styleFlag

2. Field not found: styleFlag

   at net.sf.jasperreports.engine.design.JRAbstractCompiler.verifyDesign(JRAbstractCompiler.java:258)

   at net.sf.jasperreports.engine.design.JRAbstractCompiler.compileReport(JRAbstractCompiler.java:140)

   at com.jaspersoft.ireport.designer.compiler.IReportCompiler.run(IReportCompiler.java:498)

   at org.openide.util.RequestProcessor$Task.run(RequestProcessor.java:572) at org.openide.util.RequestProcessor$Processor.run(RequestProcessor.java:997)

The exception don't make sense. If I use the field “styleFlag”(boolean) in the report I get the true or false value from the data source, but as a condition the value of the test field is not available.

By the way: The condition phrase for the style is ($F{styleFlag}.equals( true ))

Thanks
