Why will this tie not work?

[David Fedoruk]

Hello:

First, I'd like to thank the Lilypond programmers for a great job! I
finally finished typesetting two of these Scsarlatti Sonatas, one of
which was from the ubiquitous Longo edition. After sitting at
keyboard and trying to read both, the Longo edition is no longer good
enough. Its almost unreadable and it looks hideous. Lilypond manages
in three pages of easiyl readable score to do what the Longo Edition
makes almost unreadable in 4 pages. Thanks again.

Now my problem, the following lines have one tied note, the  "a" in
the Right Hand upper voice is tied to an "a" in the next bar. The only
problem I can see for Lilypond is that its at that point which the
bars of two voices merge to become one voice again. I've tried
tweaking it in various ways i.e. coding  both bars on the same like,
coding the merged voice immediately following the lower voice, nothing
seems to work.
