Hi Wenfeng,
Thanks for the quick reply. I tried out your suggestion. Changed Assign as
<assign>
<copy>
<from
expression="fn:concat(bpws:getVariableData('probeInput','probeData'),bpws:getVariableData('probeInput','probeName'))"/>
<to variable="probeInput" part="probeData"/>
</copy>
</assign>
with <xmlns:fn="http://www.w3.org/2005/02/xpath-functions";>
But unfortunately it didn't solve the problem. Still giving that error.
Anyway I have attached modified BPEL as well. Any more ideas as to how to
make this work?
Regards,
Chamith
