Yes the node name should be unique or else it will override the previous value. I will see if I can extends this blog or a new blob to resolve that issue as well. But the high level idea is to identify / generate the unique value in the repeated blocks and dynamically append that to the node key being created in dispatchOmniEvent.

Thanks for the response Nagendra, much appreciated! Since the node names are generated automatically and as duplicates, I ended up extending from OmniscriptBaseMixin(OmniscriptTypeAhead) and matching the items though their values to be updated with omniApplyCallResp.
