Thanks Sudharma for reply,
As I mentioned* "modifyAgRes.xml" *is a mock of backend service. I cannot
change the backend service. Whatever modifications I have to do is only to
main xml* "**addChild.xml**".*
Plus I think we cannot use payloadFactory this way , as number of elements
coming in input array are not fixed.It can be any number.
One more thing, Enrich mediator is behaving weirdly. For editing the
property of type "OM",
suppose property like this
<property expression="//jsonObject" name="firstResponse" scope="default"
type="OM"/>
use of below xpath sometimes works and sometimes not
*xpath="$ctx:firstResponse"*
but mostly (intermitently) it gives below error
*EnrichMediator} - Invalid Target object to be enrich. *
I am getting the similar error , even for the xpath you have suggested.
* xpath="get-property('firstResponse')/children*
With Regards,
Aditya
