I'm now very confused, as after changing a couple things trying to sort out the issue I'm now not able to add nodes at all, getting the following error:
2014-10-17 16:57:44,442 [67] ERROR SolarWinds.InformationService.Core.InformationService - Exception caught in method Create
System.ArgumentException: An item with the same key has already been added.
This seems very odd to me since Orion.Nodes has simply NodeID as it's primary key, which is something the API should be generating, no?
