In TabVoice - how to avoid: "programming error: side-axis not set for grob StrokeFinger"

[Thomas Morley]

Hi all,

if I want to print StrokeFinger in TabStaff I need to consist
"New_fingering_engraver". And it works fine, at first sight...
Alas, if there is an additional markup then I get a programming error
(even if the markup isn't printed at all).

\version "2.20.0"

\new TabVoice \with { \consists  "New_fingering_engraver" }
  { b-\rightHandFinger 1 -"foo" }

>From terminal:
[...]
atest-100.ly:269:6: programming error: side-axis not set for grob StrokeFinger.
  { b
     -\rightHandFinger 1 -"foo" }
atest-100.ly:269:6: continuing, cross fingers
[...]

Any hints why this error is generated and how to avoid?


Thanks,
  Harm
