Hello hurelhuyag,

Since this is not a bug, but rather a question, I will close this ticket. I answered your question on stack overflow: https://stackoverflow.com/questions/44580132/how-to-retrieve-indexedembedded-properties/44583503#44583503 , and if you have other problems I'll be happy to continue our discussion there.

If it turns out there is actually a bug, feel free to reopen this ticket.
