A list:reference field already gets a default "represent" attribute, as
long as the referenced table has a "format" argument. However, the
"represent" function (for any type of field) is only applied automatically
in particular contexts (e.g., SQLTABLE, the grid, and read-only forms). In
your case, you have to call it explicitly:
{{=db.course.book.represent(header.course.book)}}
