[JW Lua] Setting FCStaff:IndependentKeySig does not work

[Jan Angermüller]

Jari,

if I create a new staff with JW Lua and set IndependentKeySig=true,
then the created staff will have the option "Independent Elements -> Key 
Signature" selected,
BUT when I change the key in some measures on this staff it will affect 
the whole score,
not this staff only as it should.
If I de-select the option in the staff settings, click on ok, go back to 
the staff settings and re-select it,
it will then work fine, if I change the key signature somewhere on that 
staff.

It seems to me that although the option "Independent Elements -> Key 
Signature" is visually selected in the staff settings after running the 
script, there must be a second flag beside FCStaff.IndependentKeySig 
that needs to be set for the independent key signature to work. I tested 
it with Finale 2014d / Windows 7 / JW Lua v0.29.

Below is the code to create the independent key signature staff.
Here is also a screencam video to demonstrate the above behaviour:

All the best,
Jan


   local staffID = finale.FCStaves.Append()
   if staffID then
     local staff=finale.FCStaff()
     staff:Load(staffID)
     staff.IndependentKeySig=true
     staff:Save()
   end
