 Hi Pierre,

 This warning's caused by a typo here : pfL = { \change PIanoSingleStaff = 
 piano_lower \oneVoice }

 Eep. That’s embarrassing… Thanks for catching that.
 However, once it’s fixed, I still get a [different] error: ”not changing to 
 same context type”.

 Any help for that?

 Thanks,
 Kieren.

Hi Kieren,

it has nothing to do with your custom-contexts.
It's issue 1681
https://code.google.com/p/lilypond/issues/detail?id=1681
Workarounds are listed there.
Another one, start 'theMusic' with: 

HTH,

 Hello all,

 In the attached snippet, I’ve defined some custom contexts
 (nested/hierarchical) for piano work.
 I can’t seem to get staff switching to work correctly: I get “ cannot
 change […] none of these in my family” errors.
 Any hints would be appreciated.

 Thanks!
 Kieren.

Thanks!
I simply removed the initial \pfL, and everything seems fine.

Best,
Kieren.
