PI Vision navigation links and asset-relative displays

I am having real problems getting navigation links in PI Vision to work consistantly with regards to asset relativity.

 

This is a subset of my asset hierarchy:

 

     - Machine element [machine template]

          |- BufferSS element [buffer template]

          |- AF Server element[AFServer template]

 

I have a PI Vision display for each template and I have navigation links from the Machine display to each of the Buffer and AFServer displays.

  • When I double-click the AF Server link on my parent display, the AFServer display opens up, showing details of the AF Server child element. This is as I expect.
  • When I double-click the Buffer link on my parent display, the Buffer display opens up but it is still pointing at the parent element so most of the attributes it is trying to display don't exist!

What are the hoops I have to jump through to get this to work? Both the links have identical configuration. I have re-built the links and the Buffer display countless times, checking it works each time and then the next time I try to go there it is broken again!
