Hi, thanks for your replay. Using the debug function I obtain:

Debugger entered--Lisp error: (wrong-type-argument integer-or-marker-p nil)
  buffer-substring-no-properties(nil nil)
  noweb-tangle-chunk(#<buffer Tangle Buffer>)
  ess-eval-chunk(nil)
  call-interactively(ess-eval-chunk nil nil)

Sent the full traceback:

From: cism <cism@maxquant.i-did-not-set--mail-host-address--so-tickle-me>
To: ess-bugs@r-project.org
Subject: ess-mode 5.14; Definition new key binding in Noweb mode.


Thanks
Riccardo
