The only thing you needed to change in the if clause is the equals check to use uuids and not id because newly created items have no id before they are saved but do have a uuid .
You will still need the conceptToValidate.getConceptId() != null because the reason it is there is to ensure that when you are saving an existing item, the code doesn't end up thinking it is a duplicate because getConceptMapTypeName will always return it if you pass in an existing item's name

In theory the code is checking that if it we found a duplicate, make sure it is not the item itself we are validating that was found and this only arises for existing items that are getting edited

thanks please @wluyima for your review and response, however i think i need to hear farther from you to respond to these two comments, i think it is better either on the IRC or here; by making further clear what you are meaning in your wonderful explanation above,
thanks

i mean you still need the if(conceptToValidate.getId() != null) and not if (conceptToValidate.getUuid() != null)

ok, i think i better understand you now after the above comment, how can i implement comparison on uuids instead of ids. in this case besides what i had originally proposed as my ticket interpretation.

Your commit is fine except undoing the change NOT to replace conceptToValidate.getConceptId() != null with conceptToValidate.getUuid() != null on line 180 above in red but the equals should still use getUuid()
