It's a feature which has been requested many times. For example in these
threads:
http://groups.google.com/group/activescaffold/browse_thread/thread/6aa2ca7641d66102
http://groups.google.com/group/activescaffold/browse_thread/thread/69163d469cb07b3f
It's about rendering again a field after change a value in another field. Now
you can get it only with a line in your controller:
config.columns[:master_column].options = {:update_column => :slave_column}
Field for slave column will be rendered again when you change the value in
master column. It will work if rendering slave column only needs the value of
master column.
I haven't tried with two levels of chained fields as in second thread,
probably it needs more tweaking for that case.
I'm documenting it in the wiki:
