Error retrieving data from the payload

Question

Hi all,
I have a sample process which receive the xml payload posted (with http post) from another process. I am able to see the data in my input payload, but I am not able to use either assignment or transformation to get the value of any element from that payload. If I use the getNodeValue, I am able to see the data of each element.
e.g., the xml that was posted to this process is
=========
<?xml version="1.0" encoding="UTF-8"?>
<!-- "Stock Quotes". -->
<stockquotes>
<stock_quote>
<symbol>ABCDEFG</symbol>
<when>
<date>01/27/2001</date>
<time>3:40PM</time>
</when>
<change>-2.1875</change>
<volume>8050200</volume>
</stock_quote>
</stockquotes>
=================
In my input payload, I am seeing as
=========
<Receive_XMLNode_InputVariable>
<part name="RequestMessage">
<RequestMessage>
<stock_quote>
<symbol>ABCDEFG</symbol>
<when>
<date>01/27/2010</date>
<time>3:40PM</time>
</when>
<change>-2.1875</change>
<volume>8050200</volume>
</stock_quote>
</RequestMessage>
</part>
</Receive_XMLNode_InputVariable>
===================
But when I tried to assign symbol element to output, I am getting "com.oracle.bpel.client.BPELFault: faultName: {{http://schemas.xmlsoap.org/ws/2003/03/business-process/}selectionFailure} " error. Can anyone advise me what am I doing wrong? Thanks.

Answer 1

I added the namespace in my stockquote xml payload exactly as I used in the input xsd, and it started working.
