unable to compile master report - pls advise

[baffled]

I am trying to set up a master report with two subreports that I plan to intergrate with Spring.

I need some help because I'm having a problem compiling the master report. I'm defining the locations of the subreports as parameters in the master report - as per the Spring documentation - but iReport is not able to find the subreports using the parameters.

This is my error in iReport:

Compiling to file... c:someFolderMR_S_master.jasper  

Compiling subreports....  Unable to locate the subreport with expression: "$P{MR_S1_SUBREPORT}".

This is the jrxml of the master report:

<?xml version="1.0" encoding="UTF-8"?>
<jasperReport xmlns="http://jasperreports.sourceforge.net/jasperreports" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://jasperreports.sourceforge.net/jasperreports http://jasperreports.sourceforge.net/xsd/jasperreport.xsd" name="MR_S_Master" pageWidth="595" pageHeight="842" columnWidth="535" leftMargin="20" rightMargin="20" topMargin="20" bottomMargin="20">

The Spring side will look like this:

<bean id="MR_S_ViewPdf" class="org.springframework.web.servlet.view.jasperreports.JasperReportsPdfView">

<property name="url">
 <value>classpath:/someFolder/MR_S_master.jrxml</value>
</property>

<property name="subReportUrls">
 <map>
    <entry key="MR_S1_SUBREPORT" value="classpath:/someFolder/MR_S1_subreport.jasper"/>
   <entry key="MR_S2_SUBREPORT" value="classpath:/someFolder/MR_S2_subreport.jasper"/>
 </map>
</property>

<property name="subReportDataKeys">
 <list>
  <value>MR_S1_DATA</value>
  <value>MR_S2_DATA</value>
 </list>
</property>

<property name="reportDataKey">
 <value>MR_S_DATA</value>
</property>

</bean>

For other developer's reference:

Even though iReport can't hook up the master/detail reports for the Preview it still compiles OK and it works with Spring.
