Undo key signature doesn't work on second staff

The score fixes itself after a doLayout(), so no serious harm done.

Here's what I know so far:

Score::endCmd() is not called for undo operations, but Score::endUndoRedo is, and this is where doLayout() gets called. And it *is* getting called here. It just for some reason isn't doing the job the first time, even though a second call fixes it. gdb is not cooperating - keeps crashing in mid-session - so I can't tell more.

If I had to guess, I'd say maybe it has something to do with "generated" flags on the key sigs.

This does not currently seem to be reproducible, maybe was fixed as part of the recent change to support custom key sigs. But I don't think I'd be comfortable closing this until we see if it still works after a fix for #41291: Switching concert pitch when using transposing instruments augments the keysignature on each line..

Actually, though, while the Undo *appears* to work, it doesn't really. After the Undo, try deleting the key signature again. This time, it disappears only from the first system. I suspect this behavior is related to #41291: Switching concert pitch when using transposing instruments augments the keysignature on each line.

I do not see the same thing or I do not understand anything. Currently with the latest Nightly, and after Undo, and new deleting, it works as expected : the four sharps disapears within two systems (not only from first system)? There may be another intermediate step?

Take a look at this: an other variation probably?

The steps to reproduce:
1.Delete the "original" four sharps
2. Undo
3. Escape
4. Drag and drop two sharps KeySig
5. Undo
6. Drag and drop again the two sharps KeySig

Result: as previous attached file.

The reported regression is always the cause.
Works well on December 7.

I see the following:

1) create new score using "treble staff" template, key of E
2) click initial key signature
3) delete
4) undo
5) click initial key signature again
6) delete

Result" key signature is removed from first system only

Same result if I create "from scratch" (using Empty instead of Treble Staff template)

seems to be fixed in 084c1d856a

I can confirm that the issues as I saw them seem fixed now - thanks, Werner!

BW, typo in my response #5 - step 6 should have been "delete", not "undo". I've fixed that now, but no matter; it didn't work yesterday but does today.

Automatically closed -- issue fixed for 2 weeks with no activity.
