Exactly the info I needed, thanks! I will fix it in 4.6.2 and 4.7.

It was running into the old tag_accessories behavior of not displaying
a widget when there was no data. The fix is to change the lines in 
Vend::Interpolate::tag_accessories which used to say:

    unless ($data || $type =~ /^text|^hidden|^password/i) {
        return '' if $item;
        return '' if $name;
        return qq|<INPUT TYPE="hidden" NAME="mv_order_$attribute" VALUE="">|;
    }

to

    unless ($data || $type =~ /^text|^hidden|^password|combo/i) {
        return '' if $item;
    } 

I will probably add an explicit argument to allow the routines
to force the state, anyway. That routine is due for a major 
overhaul and has been for years.
