Hi all,
I'm experiencing the same problem here.
Please forgive me if thi mail is long, tedious and may be unnecessarily
over-detailed. My aim is to try to give all the relevant information to
you experts.

Until I had this configuration
Ubuntu 10.04 -- GNOME 2.30.2
GNU Emacs 23.1.50.1 
(x86_64-pc-linux-gnu, GTK+ Version 2.18.0)
ESS version 12.04 -- R 2.15.0

I had no problems

Now I've changed to 
ESS version 12.09 -- R 2.15.1
and I'm experiencing problems with Sweave.

Here are the lines in my .emacs file in which is written "noweb"

 (defun Rnw-mode ()
   (require 'ess-noweb)
   (noweb-mode)
   (if (fboundp 'R-mode)
       (setq noweb-default-code-mode 'R-mode)))

I tried to comment like this, as suggested by Vitalie

(defun Rnw-mode ()
   (require 'ess-noweb)
   ;;(noweb-mode)
   (if (fboundp 'R-mode)
       (setq noweb-default-code-mode 'R-mode)))

but when I open an Rnw file I cannot get the noweb mode and in messages
appears the following

> File mode specification error: (void-function noweb-mode)

Then I tried to substitute noweb-mode with ess-noweb-mode, 
as far I can understand from the announcement

(defun Rnw-mode ()
   (require 'ess-noweb)
   (ess-noweb-mode)
   (if (fboundp 'R-mode)
       (setq noweb-default-code-mode 'R-mode)))

In this case I can open a Rnw file and get all the colors for sweave
sintax and pulldown menu for "noweb" 

On the buffer 'messages' appears the following

and in ESS buffer a lot of lines ending with 
> Finished setting up ESS-mode.

I can see the 'M-x noweb-describe-mode' but there's no 
'M-x noweb-font-lock-describe-mode'. 
The only modes are:

> noweb-font-lock-minor-mode

The problem is that I cannot get Sweave to work.

On 'M-n-s' 
(that is "process this file with Sweave")
in the buffer 'messages' I get:

> Applying style hooks... done
> Sorting environment...

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

In the ESS buffer I cannot read any error message.
In R buffer I read

> > assignInNamespace(".help.ESS", help, ns=asNamespace("base"))
> options(STERM='iESS', str.dendrogram.last="'", editor='emacsclient', show.error.locations=TRUE)


Finally I tried to comment out all the lines in my .emacs like this
> ;;  (defun Rnw-mode ()
> ;;   (require 'ess-noweb)
> ;;   (ess-noweb-mode)
> ;;   (if (fboundp 'R-mode)
> ;;       (setq noweb-default-code-mode 'R-mode)))

but I stil get the same problems and messages as the case immediately above.

>From the shell everything is working fine and I can do 

R CMD Sweave Gigi\ II.Rnw

without any problem.

Any suggestion ?

Thanks in advance for your time.
