Well, you are asking for a very sophisticated functionality and
I doubt that there are systems that connect to your custom database
layout and retrieve the values you want to fill them into comboboxes
from out of the box. However SWAMP gives you the opportunity to
achieve that very easily, by using the custom actions, which are
real elegant to use. But, yes, you have to use Java up to now.
But I am sure Tom can give you a code example of how to write that
custom code and I am sure that gives you an idea of how to do
that - even in Java ;-)
