Hi Francesco,

Thanks for the very clear example. I believe that adding the :noweb
header argument as below solves your problem. I'm sorry that this is not
yet documented.

* Test

** Common part

#+srcname: common
#+begin_src sh :exports none :results silent
   VAR=ThisIsATest
#+end_src

** My shell script

#+srcname: script
#+begin_src sh :exports results :noweb :tangle my-script
   <<common>>
   date
   echo $VAR
#+end_src

#+results: script
| "Thu"         | "Dec" | 10 | "11:15:57" | "EST" | 2009 |
| "ThisIsATest" | ""    | "" | ""         | ""    |   "" |
