Question

I have a report template that has a subreport;
in main report I have some parameters that should be available in subreport too.
Main report parameter is defined like this:

<parameter name="PID" class="java.lang.Integer"/>

And in subreport I defined same parameter with the same name:

<parameter name="PID" class="java.lang.Integer"/>

And I provided parameters of master report for sub report like this: \

     <subreport>
            <reportElement x="0" y="0" width="555" height="50"/>
            <parametersMapExpression>
                 new HashMap($P{REPORT_PARAMETERS_MAP})
            </parametersMapExpression>
            <connectionExpression><![CDATA[$P{REPORT_CONNECTION}]]></connectionExpression>
            <subreportExpression class="java.lang.String"><![CDATA["subRPT.jasper"]]></subreportExpression>
     </subreport>

but this throws this:

SEVERE: null
net.sf.jasperreports.engine.JRRuntimeException: net.sf.jasperreports.engine.JRException: Incompatible java.lang.Integer value assigned to parameter PID in the subRPT dataset.

What is the problem?

Thanks

Thnak you all,
But the problem was in version miss-matching between my JasperReport library and iReport.
using same versions fixed the problem.
