Problem with org-babel-detangle

I tangeled the following org-mode file:

  #+BEGIN_SRC R :tangle /tmp/test.R :comments link
  1 + 2
  #+END_SRC
  
  #+BEGIN_SRC R :tangle /tmp/test.R :comments link
  3 + 4
  #+END_SRC

The result was:

  ## [[file:test.org][No\ heading:1]]
  1 + 2
  ## No\ heading:1 ends here
  
  ## [[file:test.org][No\ heading:2]]
  3 + 4
  ## No\ heading:2 ends here

Then I changes “3 + 4” to “3 + 5”, revisited the org buffer, and
executed `org-babel-detangle'.

Expected behavior: The second code block in org file is updated to contain
“3 + 5”.

Actual behaviour: I find myself in a buffer containing test.R, the
cursor is inside the first code block at “1”, the second code block’s
content in the org buffer is highlighted, and I have an edit buffer for
that code block.  The content of the second code block is not updated.

No error message.

Tested with a current development Emacs and the development version of
org-mode.

I think the culprit is `org-babel-tangle-jump-to-org'.  When I call it
in test.R, it does not jump to the org file as it should according to
the documentation.

When I call it with point on the first code block, it opens an edit
buffer for the second code block in the background.

When I call it with point on the second code block, it opens test.org in
the background but doesn’t do anything else.

Fixed. Thank you.

Thanks for looking into it.  Detangling seems to work now but there is
one problem left:

If I open the org-buffer and the tangled files side by side, and then
detangle, both windows show the org-buffer afterwards.  I think
detangling should leave the buffers alone.  Perhaps there is a misplaced
save-excursion somewhere?

Thanks again, Nicolas!

I cannot reproduce it, but I assume it comes from your
`org-src-window-setup' setting. For some
reason,`org-babel-tangle-jump-to-org' calls `org-src-switch-to-buffer'.

Hm, I haven’t changed the value of `org-src-window-setup' from its
default (which is `reorganize-frame').  I will look into it.
