you guessed right, thanks! Now, my example does not fail anymore, but
does not visit any node either...
I attached a new version of the test case, in case someone has the
time to help. Maybe my `apply` method is not taken into account by the
`accept` one?
Also, I could not find the source code of the finding nodes tutorial
[1]. It's written "The source code is available [here]." but "here' is
not a link. Any idea where it could be ?

Thank you again for your help
Cheers,
