Subject: 26.3; Noweb cannot execute imported file inside buffer but works fine
 during export
Date: Thu, 6 Aug 2020 12:57:26 +0545

[Message part 1 (text/plain, inline)]

I cannot use :noweb according to the documentation inside org-mode.
I get the error: "Reference 'function_name' not found in this buffer."

Steps to reproduce:
1) Start emacs with 'emacs -Q'.
2) Create the two files code.inc, and test.org

Inside code.inc:
# -*- mode: org; -*-
#+NAME: hello
#+BEGIN_SRC python :results output :exports results
print('Hello world!', end='')
#+END_SRC

Inside test.org:
#+NAME: printhello
#+INCLUDE: code.inc
#+BEGIN_SRC shell :noweb yes :results output
echo -n <<hello()>>
#+END_SRC

3) Load the following expression:
M-x: eval-expression:
(org-babel-do-load-languages
   'org-babel-load-languages
   `((python . t)))

4) Try to execute the printhello block with C-c

After Step 4) I get "Reference 'hello' not found in this buffer."
However, If I export the test.org to HTML, the text "Hello world!" is
displayed in the HTML page.
So, it is working, but not inside the buffer.
