            <bpel:finalCounterValue><![CDATA[count($input.payload/tns:employee-list/tns:employee-info)]]></bpel:finalCounterValue>
       and trying to retrieve the 2nd element using below expression.
 <![CDATA[$input.payload/tns:employee-list/tns:employee-info[$Counter]/tns:emp-id]]>

Comment 2 Gary Brown 2012-04-02 15:12:17 UTC 
Two suggestions,

1) Change the xpath expression to be:

<![CDATA[$input.payload/tns:employee-list/tns:employee-info[position()=$Counter]/tns:emp-id]]>


and if that does not work,

2) Try both variations with:

<bpelrocess name="..."
         ....
         queryLanguage="urn:oasis:names:tc:wsbpel:2.0:sublangpath2.0"
         expressionLanguage="urn:oasis:names:tc:wsbpel:2.0:sublangpath2.0">


and remove any 'queryLanguage' attribute in the remainder of the process definition.


If you could let us know the results of these two suggestions.

Hi Gary,

Sorry for the delayed reply and thanks a lot for your suggestions.

The xpath expression with [position()=$Counter] and queryLanguage="urn:oasis:names:tc:wsbpel:2.0:sublangpath2.0"
expressionLanguage="urn:oasis:names:tc:wsbpel:2.0:sublangpath2.0"

is working fine.

Thanks,
Ravi
