[Users] Loop ForEach in Orchestra component

[nguyen]

Hi, 

I am using the BPEL ForEach activity in my BPEL process. When I execute my process in the Petals bus, I got an error : the counter variable defined by ForEach is not found.

Anyone could me tell why ?

Thank you.

This is the ForEach clause in my process :

<bpws:forEach parallel="no" counterName="compteur" name="ForEachPeriode">
            <bpws:startCounterValue>
                <![CDATA[1]]>
            </bpws:startCounterValue>
            <bpws:finalCounterValue>
                <![CDATA[count($XC01PLResponse.xc01ResponsePart/ecarts/ecart)]]>
            </bpws:finalCounterValue>
            <bpws:scope>
                <bpws:assign validate="no" name="ExtraiteXC01ResultToReleveDetteResponse">
                    <bpws:copy>
                        <bpws:from expressionLanguage="urn:oasis:names:tc:wsbpel:2.0:sublang:xpath1.0">
                            <![CDATA[$XC01PLResponse.xc01ResponsePart/ecarts/ecart[$compteur]/xsd:CodePeriode]]>
                        </bpws:from>
                        <bpws:to expressionLanguage="urn:oasis:names:tc:wsbpel:2.0:sublang:xpath1.0">
                            <![CDATA[$output.ReleveDetteResponse/tns:ecarts/tns:ecart[$compteur]/tns:CodePeriode]]>
                        </bpws:to>
                    </bpws:copy>     
                </bpws:assign>
            </bpws:scope>
        </bpws:forEach>


And this is the Petals error trace :
