I didn't follow the discussion, but I tried the example and to my
surprise recent Adobe Reader versions say that there's an error in
the form. So that's something I'll have to investigate.

As for the combo box being 'empty' before you click something.
That's normal if you copy the example from the book.
Have a look at the /AP of the second [1] and the fourth box [2]:

[1]
1 1 78 58 re S

[2]
q 1 1 0 rg 0 0 50 60 re f 0 0 1 RG 2 w 1 1 48 58 re S 0.5 g 2 2 m 2 58 l 
48 58 l 46 56 l 4 56 l 4 4 l 2 2 l f 0.75 g 2 2 m 48 2 l 48 58 l 46 56 l 
46 4 l 4 4 l 2 2 l f Q /Tx BMC q 4 4 42 52 re W n q BT 1 0 0 1 8 26.41 
Tm /Helv 10 Tf 0 g (English)Tj 0 g ET Q Q EMC

That's a huge difference.

The first thing you see when you open a form, is the default appearance
of a field. Only when you click the field (changing it), Adobe Reader
creates a new appearance.

Without knowing much about the context of the project, I'd say you'd
either should take care of the default appearance, or trigger a change
(for instance with JavaScript) that causes the Reader to create the
appearance.
