[librecat-dev] my.very.deep.path in Catmandu::Fix::marc_spec

[Klee, Carsten]

Hi Nicolas!

Great, that works!

One question left:

marc_spec("245", my.title.$append)

makes 'my.title' an array. Now if I try something like

marc_spec("245$h", my.title.medium)

it will fail silently. I understand this. But shouldn't there be a warning or something? The user might think that there is no subfield 'h'.

Cheers!

Carsten
