Hi,
You have mentioned that the client didn't get the response. Could you
please try with an enclosing element?
<property name="response">
<response xmlns=""/>
</property>
<aggregate id="agg_sitemap">
<completeCondition>
<messageCount min="-1" max="-1"/>
</completeCondition>
<onComplete enclosingElementProperty="response"
expression="$body/*[1]" >
<send />
</onComplete>
</aggregate>
Thanks
