override_form_field doesn't need column, you know the column name and you can
get with active_scaffold_config.columns[name]. It could be passed so you cannot
need to get it from config, but current apps will break.
override_input (form_ui methods) get the column. They should get record,
because is not good to use @record, many active_scaffold methods should get the
record instead of lying in getting the record through @record variable.
However they don't get @record because first form_ui methods used methods like
select, textarea and so on, which lied in @record by default. It should be
changed, and it shouldn't break many apps, most apps won't add form_ui
methods, but maybe there are some plugins which need to be updated.

You can add this line:
colum = active_scaffold_config.columns[:lines]
and then it will work with ActiveScaffold without your changes.
