[ESS] Weaving: "ess-get-process: No ESS process is associated with this buffer now"

[Mathieu Basille]

Dear list,

Here is a simple 'evaluate' problem, when I want to 'weave' a document (in 
my case  using knitr, but I think it is irrelevant).

* ess-eval-region-or-line-and-step (C-return)

Right after opening a Rmd document (i.e. R not yet launched), if I use the 
general evaluation function, this works as expected: A new R is started, 
and the region or line is evaluated.

* ess-swv-weave (M-n s)

However, right after opening a Rmd document (i.e. R not yet launched), if I 
use ess-swv-weave instead, Emacs throws an error:

	ess-get-process: No ESS process is associated with this buffer now

A new R is started, but nothing happens: the document is not weaved. I have 
to do it again now that R si started to make it work. Note that if I first 
evaluate a region/line, then weaving works as expected.

Emacs: GNU Emacs 24.3.1 from Debian
ESS: 13.09-2 from ELPA

Is there a workaround for this?
Mathieu.
