Had a chat with Dinesh on the implementation that was done for Iterate Mediator for native json support. They are using jackson for keeping reference of the json payload. This has not been committed yet since approval for libraries are still pending.
This solution will resolve the above problems of : - Finding the parent element - Updating the original payload reference during iterative mediation @Kasun please advice how to proceed.
