how to use parameter in crosstab header?

[xuyun]

some parameters need to be passed as constants to fill the cross header.

but:

net.sf.jasperreports.engine.JRException:ÂReportÂdesignÂnotÂvalidÂ:Â ÂÂÂÂÂ1.ÂParameterÂnotÂfoundÂ:Âsecond_year ÂÂÂÂÂ2.ÂParameterÂnotÂfoundÂ:Âfirst_year ÂÂÂÂatÂnet.sf.jasperreports.engine.design.JRAbstractCompiler.verifyDesign(JRAbstractCompiler.java:266) ÂÂÂÂatÂnet.sf.jasperreports.engine.design.JRAbstractCompiler.compileReport(JRAbstractCompiler.java:143) ÂÂÂÂatÂnet.sf.jasperreports.engine.design.JRDefaultCompiler.compileReport(JRDefaultCompiler.java:105) ÂÂÂÂatÂnet.sf.jasperreports.engine.JasperCompileManager.compileReportToFile(JasperCompileManager.java:127) ÂÂÂÂatÂnet.sf.jasperreports.engine.JasperCompileManager.compileReportToFile(JasperCompileManager.java:109) ÂÂÂÂatÂit.businesslogic.ireport.IReportCompiler.run(IReportCompiler.java:478) ÂÂÂÂatÂjava.lang.Thread.run(UnknownÂSource)

If you want to use report parameters inside a crosstab, you'd need to pass it as a crosstab parameter:

Code:

<crosstabParameter name="first_year" class="..">
  <parameterValueExpression>$P{first_year}</parameterValueExpression>
</crosstabParameter>

Thanks, it works, although I don't understand why use crosstabParameter to adapt parameter(sounds like global variable and local variable).

And iReport not support yet.

You can define crosstab parameters selecting the crosstab element and opening the element properties dialog.
