Hi,

I downloaded the petals-se-orchestra-1.0.2-SNAPSHOT from the site svn://svn.forge.objectweb.org/svnroot/petals, compiled by mvn and deployed in my petals instance.
However, I got always the error : "receive an ERROR status :{http://docs.oasis-open.org/wsbpel/2.0/process/executable}selectionFailure" with the ForEach bpel clause.

This is my bpel code : 

Code:

<bpws:forEach parallel="no" counterName="counter" name="ForEachPeriode">
            <bpws:startCounterValue>
                <![CDATA[1]]>
            </bpws:startCounterValue>
            <bpws:finalCounterValue><![CDATA[3]]></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[$XC01PLResponse.xc01ResponsePart/ecarts/ecart[$counter]/xsd:CodePeriode]]>
                        </bpws:from>
                        <bpws:to expressionLanguage="urn:oasis:names:tc:wsbpel:2.0:sublang:xpath1.0">
                            <![CDATA[$output.ReleveDetteResponse/tns:ecarts/tns:ecart[$counter]/tns:CodePeriode]]>
                        </bpws:to>
                    </bpws:copy>
</bpws:assign>
            </bpws:scope>
        </bpws:forEach>


 

And the error given by Petals is :

But when I replace the ForEach bpel clause by a sequence of copy clauses. It works correctly !

Code:

<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[1]/xsd:CodePeriode]]>
                        </bpws:from>
