Selection Failure error while using SUM expression - 11g

Question

Hi,
I am using following expression to calculate SUM of child node values. It works in 10G, but errors our in 11g.
Anyone has any workaround?
Expression:
<copy>
<from expression="sum(bpws:getVariableData('Invoke_ebs_get_order_data_ebs_get_order_dataSelect_OutputVariable','XwCoiwsOrderHeadersVCollection','/ns4:XwCoiwsOrderHeadersVCollection/ns4:XwCoiwsOrderHeadersV/ns4:xwCoiwsOrderLinesVCollection/ns4:XwCoiwsOrderLinesV/ns4:orderedQuantity'))"/>
<to variable="p_total_ordered_qty"/>
</copy>
Error Message:
com.oracle.bpel.client.BPELFault: faultName: {{http://schemas.xmlsoap.org/ws/2003/03/business-process/}selectionFailure}
Thanks,
Naveen

Answer 1

Gaurav,
It didn't work.
No Compilation error but failed while executing in EM.
Invalid XPath expression. an error occurs while parsing XPath expression sum('Invoke_ebs_get_order_data_ebs_get_order_dataSelect_OutputVariable','XwCoiwsOrderHeadersVCollection','/ns4:XwCoiwsOrderHeadersVCollection/ns4:XwCoiwsOrderHeadersV/ns4:xwCoiwsOrderLinesVCollection/ns4:XwCoiwsOrderLinesV/ns4:orderedQuantity'). The XPath expression was invalid; the reason was: Parse Error in sum function.. Check the detailed root cause described in the exception message text and verify that the XPath expression named in the error message is correct. The XPath expression is defined in the BPEL process. }
