BPEL engine lost the payload's namespace

Question

Hi I have a service sending an async reply. When the message is received the payload seems to have lost the namespace declaration - so subsequently causing a selectionFailure (I'm using version 10.1.3.1.0 - this worked in 10.1.2.0.2)
response definition:
<definitions......>
<import namespace="http://xmlns.oracle.com/shared/Trade" location="shared/wsdl/Trade.wsdl"/>
<portType name="StoreTradeCallback">
<operation name="onResult">
<input message="common:TradeToken"/>
</operation>
</portType>
</definitions>
response example:
<outputVariable>
<part xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" name="payload">
<tradeId xmlns="http://www.ghc.com/trade">183</tradeId>
</part>
</outputVariable>
received definition:
<process ...>
<partnerLinks/>
<variables>
<variable name="tokenVariable" messageType="common:TradeToken"/>
</variables>
<correlationSets>
<correlationSet name="CorrelationSet" properties="common:ident"/>
</correlationSets>
<sequence name="main">
<sequence name="storeTrade">
<receive name="receiveStore" partnerLink="StoreTrade"
portType="ns3:StoreTradeCallback" operation="onResult"
variable="tokenVariable" createInstance="no">
<correlations>
<correlation initiate="yes" set="CorrelationSet"/>
</correlations>
</receive>
received example:
<?xml version="1.0" encoding="UTF-8" ?>
<tradeId>183</tradeId>
Note: The correlationSet fails to initiate too unless I remove the namespaces from the alias query...
<bpws:propertyAlias propertyName="tns:ident" messageType="tns:TradeToken" part="payload"
query="/tradeId"/> <!-- namespace removed from query.... -->
Any ideas what's going on? What's munching the namespaces? Anyone seen this behaviour?
Thanks,

I've worked round the issue by changing the idiom from async reply to sync reply.
Odd!
But I'm now run into another similar problem. I invoke an service with this:
<tokenStatusVariable>
<part xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" name="payload">
<tradeId xmlns="http://www.ghc.com/trade">197</tradeId>
</part>
<part xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" name="status">
<statusId xmlns="http://xmlns.oracle.com/HandleTradeEvent">9</statusId>
</part>
</tokenStatusVariable>
The service receives this:
<statusVariable>
<part xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" name="payload">
<tradeId>197</tradeId>
</part>
<part xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" name="status">
<statusId xmlns="http://xmlns.oracle.com/HandleTradeEvent">9</statusId>
</part>
</statusVariable>
i.e. my namespace has just vanished again!!!!
Has anyone got any ideas?
