Hi there, is there a way to know the 'Original' copy vs the 'cloned' copy? I am able to retrieve the Weak Reference relation by using GetParents() method. Based on this post:- https://vcampus.osisoft.com/discussion_hall/development_with_osisoft_sdks/f/28/p/5328/28051.aspx#28051 Now, with all the AfElement that I know. I want to mark a property to say 'This is a weak ref' on cloned copy but not the original. How can I do that? Many thanks!
