Hello,

I'm trying to iterate a List from a Webservice SOAP with ForEach

<bpel:forEach parallel="no" counterName="i" name="ForEach">
            <bpel:startCounterValue>
                <![CDATA[1]]>
            </bpel:startCounterValue>
            <bpel:finalCounterValue><![CDATA[count($SAPCCResponse.centroCostoResponse/return/zcoCecos/item)]]></bpel:finalCounterValue>
            <bpel:scope>
                <bpel:assign validate="no" name="Assign1">


                    <bpel:copy>
                        <bpel:from part="centroCostoResponse" variable="SAPCCResponse">
                            <bpel:query queryLanguage="urn:oasis:names:tc:wsbpel:2.0:sublang:xpath2.0"><![CDATA[return/zcoCecos/item[$i]/Ceco]]></bpel:query>
                        </bpel:from>
                        <bpel:to part="payload" variable="CentroCostoLinkResponse">
                            <bpel:query queryLanguage="urn:oasis:names:tc:wsbpel:2.0:sublang:xpath2.0">
                                <![CDATA[ItabCecos/item[number($i)]/Ceco]]>
                            </bpel:query>
                        </bpel:to>
                    </bpel:copy>
                </bpel:assign>
            </bpel:scope>
        </bpel:forEach>


But when I consume de Bpel process throws an exception:


*I changue to 2.0   urn:oasis:names:tc:wsbpel:2.0:sublang:xpath2.0*
16:18:36,254 INFO  [UDDIClerk] entityKey uddi:riftsaw.jboss.org:service

Any Idea why I get this error and the Bpel Process don't operate.

Thanks
