Replace Genre (displayFormat)

[ischowam]

Hello

I am not really interested in the Genre data. It is "there", but I am not maintaining it.
BubbleUpnP is showing it in the Now Playing view only.

Now I thought to replace it with "Publisher" and "Comment", if available, or otherwise I keep Genre.
My idea is to do it via Genre.displayFormat

So I added Publisher and Comment into the itemTags-property and tried it with
tagFormat: Genre.displayFormat={$publisher^^ - ^$comment}

With that I see now the comment (if available) in Now Playing, but never the "Publisher".
If comment is empty, I see the Genre.

I’ve done a lot of tinkering and digging around, but I just can’t get it to work.

Is my approach wrong or am I doing something wrong?

Thanks for any hint.

Georg
