Hello, please consider attached example Org document 'ex.org'. There seems to be a problem when tangling a source block with noweb reference, without it source block is tangled fine. Two examples are also attached. Emacs version: 24.4.50 (trunk rev. 116991); org-mode: Org-mode version 8.2.5h (release_8.2.5h-991-g06c947 @ /usr/share/emacs/site-lisp/org/) --- WBR, Vladimir Lomov -- Anyway, I keep picturing all these little kids playing some game in this big field of rye and all. Thousands of little kids, and nobody's around -- nobody big, I mean -- except me. And I'm standing on the edge of some crazy cliff. What I have to do, I have to catch everybody if they start to go over the cliff -- I mean if they're running and they don't look where they're going I have to come out from somewhere and catch them. That's all I'd do all day. I'd just be the catcher in the rye. I know it; I know it's crazy, but that's the only thing I'd really like to be. I know it's crazy. -- J.D. Salinger, "Catcher in the Rye"
