Hi, 

  I faced the same problem, you can try to rewrite the "to" as following.

> <bpws:to part="payload" variable="output">
> <bpws:query 
queryLanguage="urn:oasis:names:tc:wsbpel:2.0:sublang:xpath1.0"><![CDATA[$output.payload/tns:result]]></bpws:query>
> </bpws:to>

 <bpws:to part="payload" variable="output" query="/tns:result"/>

Anyway, I don't want to be like that... everytime do it manually... 
anybody can help?
