New issue 2866 by address@hidden: A hidden note blocks beams from  
drawing
http://code.google.com/p/lilypond/issues/detail?id=2866

Reported by James Harkins:
The beams on the two e's are omitted in this tiny example.

\relative c' { r8 \hideNotes f8 \unHideNotes e8. e16 e2 }

The beams are *not* omitted in this tiny example.

\relative c' { r4 e8. e16 e2 }

Workaround  suggested by David Kastrup:

\once\hideNotes does not help, but after applying the patch for
Issue 2717 <URL:http://code.google.com/p/lilypond/issues/detail?id=2717>

\relative c' { r8 \single\hideNotes f8 e8. e16 e2 }

will do the trick.  Note that the patch is still under discussion, so
the name could change.

You could, however, still harvest the current definition of \single from
the patch and use that in your music.  As it is a Scheme-only patch, it
should work fine by just putting the definition in your file, without
needing to change LilyPond itself.
