Cross Staff Beaming issue

• Feb 25, 2009 - 07:38

Cross Staff Beaming is great, but there is a bug on it:

1. It looks good when you left one beamed note on original staff. See attached pic 1.
2. The note stems went to nowhere if all beamed notes crossed over, see pic 2.
3. Manually adjust the beam location before crossing, then it looks better, but the note stems on wrong side of note, pic 3.

This happens on both 0.9.4 and 0.9.5

When I tried cross staff beaming, I found that going down went as expected, but going up gave the weirdest results. The change would not be visible at once, and after selecting another note, the affected note would appear on the wrong line. The following demonstrates it:

1. Open the attached document "Test.mscz"
2. Click on the first G in the lower staff
3. Give the command for cross staff beaming (ctrl-shift-up, or cmd-shift-up in my case). Note that there is no visible change
4. Click elsewhere, or type the left-arrow: suddenly the note selected in step 2 will move to a higher E in the upper staff, while the stem stays in the lower staff. The note can no longer be selected by clicking.
5. Now select another note in the same beam and type 'x': suddenly everything is all right.

Test environment: MuseScore 0.9.5, MacOSX 10.5.8, iBook G4
