Great. "Inline Relational Record Editing" was the topic of my diploma
thesis as well. What is the title of your thesis?

1:n relationships do not offer such behaviour in general. If you want to
relate one publisher to many books on the other hand, it's not a 1:n
anymore, but a m:n relationship.

What happens if you select one of the records in the selector-box? Do
you get any errors (e.g. JavaScript errrors)?

Why? Only the following model is necessary:
[book] --- 1:n ---> [intermediate table] <--- 1:n --- [publisher]
