I'm trying to create an NSMappingModel manually between two models, but it's

It might be because Apple's way of alloc-ing the field editor on the spot may
not be such a good idea. If I remember correctly, it didn't work for me. That
may be the cause of your problem.
So my suggestion is: Try making an instance variable for the NSTextView, and
create it once in -init or
bind the selection of the popup to a variable and then observe
that variable via KVO. I did that on a single NSPopUpButton, you would
still need to get the affected row.

Use a cell to draw your text and call -setBackgroundStyle: on it with
