[JW Lua] Weird accidental behaviour

Wed Jul 8 15:57:13 CEST 2020

I just tried running your script without modifications and it detected the
FCAccidentalMod just fine. Steps:

1. Open accidtest.musx
2. Open JW Lua and paste in your script.
3. Run it . (Nothing detected.)
4. Move one of the accidentals.
5. Run it. (Detected.)

I then modified your script slightly to use a separate accmod2 for the 2nd
note. This works better. It looks like FCAccidentalMod doesn't work quite
right if you LoadAt for one note then reuse the same instance to LoadAt
another note.

I'm wondering if your basic problem is that after saving the accimod you
are not setting the entry's note flag. (There is a function to do this.)
Generally speaking, you can find out what your code is not doing by using
the text dump plugin to compare a manual change in Finale with your
script's changes. If you make the exact same manual change as you want from
your script, you can find out any discrepancies.
