OK, my artist field is now like this: "artist1, artist2"
and I want to create multivalue fields by replacing the ", " with "\\"'
When I do this manually in the artist field everythings works fine and in the extended tags I see two artist fields.
But when I use the replace action to do this, the result looks the same, but in the extended tags there is 1 artist field showing "artist1\\artist2"
Why don't I get a multivalue field using the replace action?
Some further experimenting:
When I press save with a single file file selected, the "artist1\\artist2" field becomes true multivalue,
but when I press save with multiple files selected, the field stays the same.
