Changes to staff transposition (and other properties) not reflected in linked parts
Ubuntu 14.04, GIT commit: 9341f4e
1) new score, flute, key of F
2) add notes for an "F" scale
3) generate parts
4) staff properties
5) change instrument to Bb clarinet
Result: notes and key signature transpose in score, as they should. But view the part, and you'll see the notes is transposed but the key is not. Also, the octave is wrong for the "C". Press the "Concert Pitch" button while viewing the part and the notes display with the correct pitches, and the key signature remains "F".
If you check Staff Properties in the part, you'll see that it is still set to Flute, with no transposition. The notes transpose because the tpc's info was linked, but since there is no transposition data, the keys did not transpose. Not sure why the octave is off on the "C", but it seems a not surprising consequence of the tpc's being out of sync with the transposition info.
If you change other staff properties, like number of staff lines, you'll see these are not linked either.
At the very least, I think a change to transposition must affect linked parts. BTW, if you change the instrument in the part, everything works correctly - you don't get a second transposition.
I'm not sure if linking changes to staff transposition makes sense for linked staves of different staff types within a score, however - eg, a guitar staff & linked tab staff. I gather that there is some possible association between transposition and capo, but I don't know what's expected here.
