[O] [bug] Problem when tangling into LaTeX

[Sebastien Vauban]

#+TITLE:     Noweb references in LaTeX document
#+DATE:      2012-01-30

* Summary

** Problem

I use 3 chunks of LaTeX code which I wanna insert in a LaTeX document.

While 1 of them is correctly tangled into the LaTeX document, the 2 others
generate errors when C-c C-v C-t'ing:

    "if: reference '<<who' not found in this buffer"

and, if I temporarily replace `<<who()>>' by `<<who>>', I get the next error:

    "if: reference '    <<solde' not found in this buffer"

What I don't understand is that there is no -- sorry, I mean: I don't see --
the difference between the 3 noweb references. They all seem correctly
written...

** Note

Remember that, up to now, such a document *must be first tangled* and then
post-processed via =PDFLaTeX=. It can not be exported directly to PDF/HTML 
(=args
out of range= error).

* Example

** Part 1
#+name: who
#+begin_src org :results latex
1111ToMe
#+end_src

** Part 2
#+name: before
#+begin_src org :results latex
2222BeforeDate
#+end_src

** Part 3
#+name: solde
#+begin_src org :results latex
3333Rest
#+end_src

** Composed letter
#+begin_src latex :noweb yes :tangle yes
\documentclass{article}
\usepackage[utf8x]{inputenc}
\usepackage[T1]{fontenc}

\begin{document}

\begin{textblock}{85}(98,35)
\titlebox{9.4cm}{Foo}{% HERE 1111 <<<<
<<who()>>
}
\end{textblock}

\begin{textblock}{110}(25,195)
    Some sentence
    <<before()>> \hfill{}% HERE 2222 <<<<
    <<solde()>> EUR% HERE 3333 <<<<
\end{textblock}

\end{document}
#+end_src

Best regards,
  Seb
