[O] new exporter: exporting subtree with "outside calls"

[Andreas Leha]

Hi all,

I experience problems with the new export engine (accessible via
org-export-dispatch).

When I limit the export to the current subtree,
the export fails with
,----
| if: reference 'foo' not found in this buffer
`----
when 'foo' is the name of a source block defined outside of that subtree
but called inside.

Here is an example:  How do I export the first subtree only with the new
exporter?

,----[ test.org ]
| #+PROPERTY: session *R:2*
| 
| 
| * Test new LaTeX exporter
|   #+call: data_generation() :results silent :exports none
| 
|   The plot looks like this:
|   #+begin_src R :results graphics :file test.png :exports results
|     plot(x)
|   #+end_src
| 
|   #+results:
|   [[file:test.png]]
| 
|   
| 
| * Generate the data                                              :noexport:
|   #+name: data_generation
|   #+begin_src R
|     x <- rnorm(10)
|   #+end_src
`----

Best,
Andreas
