Hi,
I had a somewhat same error last week. It looked very strange to me, but
the real error was some lines above in the log! The assign you are using
now is the same as in the previous message, but written in a different
way.. I think in a good way ;)
According to your error in the previous message, it looks like the
variable ca-response don't have the part payload. Can you confirm that?
Or can you please post the used WSDL?

I tried modifying the assign statement in BPEL to read like this:
<bpel:assign>
<bpel:copy>
<bpel:from variable="ca-response" part="payload"/>
<bpel:to variable="response" part="payload"/>
</bpel:copy>
</bpel:assign>
with this I see the following exception, I'm obviously doing something wrong,
but haven't been able to point out the issue:
