active_scaffold_config.list.columns = [:col1, :col2, ...] does not work in a before filter. I think I found the correct class in the AS source and there's comments that imply the are preventing that type of behavior on purpose. I have not investigate the set_columns method.
I'll report back if I have any success with that.
