Its possible to select non-atomic tags like folders, UDTs and arrays in the tag change event selector window. (The 'check tag paths' button doesn't give any error on these tags). However I was wondering what the 'The newValue Object' and the 'The event Object' will return in case of these non-atomic tags? Does it trigger when any one of the tags in the array, or UDT or folder changes?
