Subreport is not displayed

I started working with subreports in JapserReports. At the beginning I would like to do something very simple. This is xml code of my subreport:

    <?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="Rb50dane" pageWidth="842" pageHeight="595" orientation="Landscape" columnWidth="802" leftMargin="20" rightMargin="20" topMargin="0" bottomMargin="0">
    <property name="ireport.zoom" value="1.0"/>
    <property name="ireport.x" value="0"/>
    <property name="ireport.y" value="0"/>
    <field name="column01" class="java.lang.String"/>
    <background>
        <band splitType="Stretch"/>
    </background>
    <title>
        <band splitType="Stretch"/>
    </title>
    <pageHeader>
        <band splitType="Stretch"/>
    </pageHeader>
    <columnHeader>
        <band splitType="Stretch"/>
    </columnHeader>
    <detail>
        <band height="22" splitType="Stretch">
            <textField>
                <reportElement x="208" y="0" width="257" height="22"/>
                <box>
                    <pen lineWidth="3.25"/>
                    <topPen lineWidth="3.25"/>
                    <leftPen lineWidth="3.25"/>
                    <bottomPen lineWidth="3.25"/>
                    <rightPen lineWidth="3.25"/>
                </box>
                <textElement/>
                <textFieldExpression class="java.lang.String"><![CDATA[$F{column01}]]></textFieldExpression>
            </textField>
        </band>
    </detail>
    <columnFooter>
        <band splitType="Stretch"/>
    </columnFooter>
    <pageFooter>
        <band splitType="Stretch"/>
    </pageFooter>
    <summary>
        <band splitType="Stretch"/>
    </summary>
</jasperReport>

And this is part of my main report code:

<detail>
        <band height="22" splitType="Stretch">
            <subreport>
                <reportElement x="208" y="0" width="257" height="22"/>
                <dataSourceExpression><![CDATA[]]></dataSourceExpression>
                <subreportExpression class="java.lang.String"><![CDATA["C:\\Users\\mg\\Jasper\\Rb50data.jasper"]]></subreportExpression>
            </subreport>
        </band>
    </detail>

As you can see I do not use any parameter in my subreport. Unfortunately, in iReport after compiling my main report, subreport is not displayed, but when I try to run my subreport separately it works.

In my test I use empty data source. I just want to see the column with null value to find out whether the subreport works fine.

I'd try adding something in the dataSourceExpression of the parent report. Maybe send the whole data source by using *
