Hi,
I have in an org file the following
#+PROPERTY: header-args:R :session *R-cities*
I open a R session, rename it to *R-cities*, open the org file. If I go
then to a babel block and send it to the R session with C-c C-c it is
sent to the right session.
But: if I edit the block with org-edit-src-code (C-c '), then the source
buffer has no R-session attached and I'm asked which one I want to use.
Is this maybe a small bug?
I'm using:
Org mode version 9.0.9
GNU Emacs 25.2.1 (x86_64-unknown-linux-gnu, GTK+ Version 3.22.16) of
2017-07-16
Many thanks in advance.

If you have more than one session running, it is a consequence of ESS's handling of multiple sessions.
This issue is closely related to the one in this longish thread:
Subject: org babel, ess, R
Date: Sat, 1 Jul 2017 07:06:43 +0530
Message-ID: <CAFVt51KWV2OUFB5NB4tSsxz+rJdftB3DRNKurfac4AdiRT0jrw@mail.gmail.com>
Getting stuff like this to work seamlessly looks to be a good challenge. I notice that this function
,----[ C-h f org-babel-R-associate-session RET ]
| org-babel-R-associate-session is a compiled Lisp function in
| ‘ob-R.el’.
|
| (org-babel-R-associate-session SESSION)
|
| Associate R code buffer with an R session.
| Make SESSION be the inferior ESS process associated with the
| current code buffer.
|
| [back]
`----
looks like it aims to do something like what is needed, but never got used. I suspect the author took a few steps in this direction and saw it was going to be a heavy lift and gave up.
It isn't obvious to me how one would put a ruleset together that would work well across a variety of situations with multiple sessions. That is, you may want :session headers to be honored or ignored depending on circumstance.
HTM,
Chuck

Yes, I have. That explains at least a little bit the issue... Thanks for
your very informative answer.
