This is a problem in Unity - the dee model objects are all allocated in such a way that we can only wrap them in an adapter when adding them to the introspection tree. This happens each time an autopilot query arrives, so the Ids are different for each query, which in turn makes trouble for autopilot.

Probably the only way to fix this is to export the dash result objects differently from within Unity - not as separate objects in the object tree, but as an array of results from one of the existing dash objects.
