java.lang.String cannot be cast to java.lang.Integer

[rene.beck]

Hi

I have a parameter mand_id

    <parameter name="mand_id" class="java.lang.Integer">
        <parameterDescription><![CDATA[MandId]]></parameterDescription>
    </parameter>

and I pass this parameter to a subreport.
                <subreportParameter name="MAND_ID">
                    <subreportParameterExpression><![CDATA[new Integer(Integer.valueOf($P{mand_id}))]]></subreportParameterExpression>
                </subreportParameter>

If I run this report on windows in the jaspersoft Studio, it runs perfect.

 

runnning on linux I get this exception and I don't know how to fix.

java.lang.RuntimeException: net.sf.jasperreports.engine.fill.JRExpressionEvalException: Error evaluating expression for source text: new Integer(Integer.valueOf($P{mand_id}))

[gustavofarias]

what's the point of this?

new Integer( Integer.valueOf( $P{mand_id} ) )

If mand_id is already an Integer, why all this?

 

What's the type of the parameter in the subreport (MAND_ID)?

[rene.beck]

in the subreport mand_id is also INTEGER

 <parameter name="MAND_ID" class="java.lang.Integer">
  <parameterDescription><![CDATA[mand_id aus Hauptreport]]></parameterDescription>
 </parameter>

 

 

even if I pass directly the parameter mand_id from the main report (which is also Integer) I get the same error, but only on linux.

 

anyway, I found a workaround for my problem. I defined a Variable

 <variable name="mandIdInt" class="java.lang.Integer">
  <variableExpression><![CDATA[new Integer(Integer.valueOf($P{mand_id}))]]></variableExpression>
 </variable>
 

and pass this to the subreport.
