ProjectCenter & Emacsclient editor setup?

[Csanyi Pal]

Hi,

I have installed gnustep from the 
deb http://coyote.octets.fr/pub/gnustep/packages/wheezy/amd64/ ./

repository:
ProjectCenter version 0.6.1

I have the environment variable EDITOR setup in files:
~/.xinitrc
and
~/.xsessionrc
export ALTERNATE_EDITOR="emacs" EDITOR="emacsclient" VISUAL="emacsclient"

I first start Emacs.
I have setup in ~/.emacs file for emacs server-mode:
 '(server-mode t)

When I click in ProjectCenter in the main window browser on the
Supporting Files/GNUmakefile,

a new Emacs window appeares with the following message:

Warning (server): Unable to start the Emacs server.
There is an existing Emacs server, named "server".
To start the server in this Emacs process, stop the existing
server or call `M-x server-force-delete' to forcibly disconnect it.

I expect that that instead of appearing a new Emacs window I can edit
the GNUmakefile in the existing Emacs window.

Why doesn't happen things this way?
