This is exactly the approach I tried first. In my naive mind, this
looks to be the most
natural way, and I thought it SHOULD work. However, it did not work on
my computer...,
and that is why I started to invent ugly work-arounds...

Please see attached a minimal example to reproduce the error message:
object 'x' not found.

Thank you very much!
Lei
