adding a List of JTextField to the GUI

I've tried moving the loop to before or after the group layout is set, no
change. I'm printing the record instance, and its member data.size() to
the console, and those look ok. I'm just not able to add components with
a loop.

Hmm, too tired right now, but maybe I'll play around with matisse.

any pointers appreciated!
