No, you have to set the same id as AS set usually. If you are using master
branch you will get an options hash instead of input_name, so it's easier:
def value_form_column(record, options)
if record.name
select :record, :value, options_for_select(User::LIST[record.name]), options
....
If you are using rails-2.3 branch, you can use active_scaffold_input_options to
get the id:
def value_form_column(record, input_name)
column = active_scaffold_config.columns[:value]
id = active_scaffold_input_options(column)[:id]
if record.name
select :record, :value, options_for_select(User::LIST[record.name]), :name =>
input_name, :id => id

You get that error because cannot get the field to update, because you are not
using AS id schema.
