That did the trick. I'll be looking form caching down the road.
Sometimes it's important to get fresh data from the DB into the form
and sometimes it's not. I'll have to study TG's caching mechanisms. I
think it would be good to define a form that is cached with widgets
that are dynamic. And those dynamic widgets could even have criteria
for repopulating.
Thanks for your help. You saved me much time.
