[JW Lua] Weird accidental behaviour

[Jan Angermüller]

Thanks a lot, Robert, for you super quick replies!

But can I detect this automatically in JW Lua? Maybe you use other 
functions/flags in your plug-in?

When I run this JW Lua code, it always return false when trying to load 
an accidental mod.
So I haven't been able to detect an existing accidental mod here.

for e in eachentry(finenv.Region()) do
     if not e:IsRest() then
         local accmod=finale.FCAccidentalMod()
         accmod:SetNoteEntry(e)
         local note=e:GetItemAt(0)
         print(accmod:LoadAt(note))
         print(accmod.HorizontalPos)
         note=e:GetItemAt(1)
         print(accmod:LoadAt(note))
         print(accmod.HorizontalPos)
     end
end

Best,
Jan
