NullPointerException when publish ReportBook with the same report as template

[gengon555]

Hi!

I have ReportBook which consists of two same reports with different input data. That is:

            <part uuid="f771936d-e47f-4ecb-abb9-b205bff40816">
                <p:subreportPart xmlns:p="http://jasperreports.sourceforge.net/jasperreports/parts" xsi:schemaLocation="http://jasperreports.sourceforge.net/jasperreports/parts http://jasperreports.sourceforge.net/xsd/parts.xsd">
                    <subreportParameter name="REPORT_CONNECTION">
                        <subreportParameterExpression><![CDATA[$P{REPORT_CONNECTION}]]></subreportParameterExpression>
                    </subreportParameter>
                    <subreportParameter name="OPER_GROUP">
                        <subreportParameterExpression><![CDATA[1]]></subreportParameterExpression>
                    </subreportParameter>
                    <subreportExpression><![CDATA["test1.jasper"]]></subreportExpression>
                </p:subreportPart>
            </part>
            <part uuid="af7aceb6-10ce-4732-a263-411a37c124ac">
                <p:subreportPart xmlns:p="http://jasperreports.sourceforge.net/jasperreports/parts" xsi:schemaLocation="http://jasperreports.sourceforge.net/jasperreports/parts http://jasperreports.sourceforge.net/xsd/parts.xsd">
                    <subreportParameter name="REPORT_CONNECTION">
                        <subreportParameterExpression><![CDATA[$P{REPORT_CONNECTION}]]></subreportParameterExpression>
                    </subreportParameter>
                    <subreportParameter name="OPER_GROUP">
                        <subreportParameterExpression><![CDATA[2]]></subreportParameterExpression>
                    </subreportParameter>
                    <subreportExpression><![CDATA["test1.jasper"]]></subreportExpression>
                </p:subreportPart>
            </part>
        </groupHeader>

Should I clone the report to test2.jasper and change the name of the second report in the reportbook (test1.jasper -> test2.jasper), no error occurs.

The workaround by cloning reports is not solution, because in other cases I need to add the same report with different params in one reportbook many times.
