Have you tried to redirect the output to the tty/console?
in class/41-warning.sh we do this
out=$(tty)
dialog ...... > $out

All shell variables you define in class/*.var are available in the
customization scripts.

Not sure if this still works, but try to name your hook
config/hooks/taskname.classname.sh

Oh, that's what I just suggested.
Maybe just add a hook
hooks/configure.DEFAULT.sh containing your variable definitions or just
source /tmp/myvars.sh in this hook.
OR name the hook hooks/defvar.DEFAULT.sh
