JasperReports: Report with xml subreport xPath - xpath

Question

I have a master report that call a sub report when a group change.
I pass two XML Documents that are the different datasource for the master and the sub report.
The subreport is printing , but every subreport lose the 2 first records of the data.
I think is a wrong xPath expression, but i try several solution but no one works for me.
The snippet of master's report jrxml file:
<queryString language="xPath"><![CDATA[riepilogo-ec/dettagli/dettaglio]]></queryString>
<group name="GiroGroup" isStartNewColumn="false" isStartNewPage="false"
isReprintHeaderOnEachPage="true" keepTogether="true">
<groupExpression>
<![CDATA[$F{giro}]]>
</groupExpression>
<groupFooter>
<band height="20" isSplitAllowed="false">
<subreport>
<reportElement isPrintRepeatedValues="true" x="0" y="0" width="507" height="10"

<subreportParameter name="REPORT_DATA_SOURCE">

I see thath if i put subreport in the summary it works, so is a problem of the group footer, any idea?
I try to debug Jasperreport library, and i see when xPathExecuter.selectNodeList(document,selectExpression) is called
it return the right number of node but the first node in the list is not the first node in the xml file thath rappresent the xPath expression.
How i can get the nodes in the right order?
