!? user-error: Not in a sub-editing buffer

[Gregor Zattler]

Dear Emacs users,

since today I cannot save buffers via ^x^s but Emacs says:

„user-error: Not in a sub-editing buffer“

When I do ^x # (server-edit) in order to leave emacsclient 
Emacs asks if I want to save the buffer.  

This is strange since I build Emacs from sources and rgrep does
neither find „Not in a sub-editing buffer“ in Emacs sources nore
under ~/.emacs.d/

Any ideas?



This is GNU Emacs 25.0.50.6 (i686-pc-linux-gnu, GTK+ Version 3.14.5) of 2015-04-27 on boo
with loads of packages.

Ciao, Gregor

This seems to be an error in org-mode (other source directory) it's
already asked on the org-mode mailinng list.

Sorry for the noise, Grfegor

Just FWIW and the result of a very quick-and-dirty Duck search:

this message lives (among possibly a myriad of other places, what
do I know) in Org-mode:

  (defun org-edit-src-save ()
    "Save parent buffer with current state source-code buffer."
    (interactive)
    (unless (org-src-edit-buffer-p) (user-error "Not in a sub-editing buffer"))
    (set-buffer-modified-p nil)
    (let ((edited-code (org-src--contents-for-write-back))
          (beg org-src--beg-marker)
          (end org-src--end-marker)
          (overlay org-src--overlay))
      (with-current-buffer (org-src--source-buffer)
        (undo-boundary)
        (goto-char beg)
        (delete-region beg end)
        (when (org-string-nw-p edited-code) (insert edited-code))
        (unless (bolp) (insert "\n"))
        (move-overlay overlay beg (point))
        (save-buffer))))

which is, AFAICS there for editing a source block in the source's major
mode: this makes the error message more understandable.

To debug it further you could (a) toggle-debug-on-error; (b) look for
the existence (and state) of a (presumedly) buffer local variable
org-src-edit-buffer-p in the buffer you're trying to save.

Take with a fist of salt.
