Getting Values of All Children from an Element StreamSet in PI Web API

I'd like to get the values of all attributes, from all elements under a specific element using the StreamSet controller of the PI Web API.


So in this case, I have a layout similar to the following...


Asset A

    Asset B

        Asset C

        Asset D


And when I ask for the StreamSet for Asset A, I'd like to also see all of the vaues on B, C & D.


I would have thought that searchFullHierarchy would have done this, but it doesn't seem to do anything at all - it doesn't present any new attributes, regardless of where I use it. Accessing the streamset for Asset C shows me all of the attributes of that element, but I can't ask for the attributes of Asset C from Asset B.


If it helps (just in case this is/was a bug), the server version is
