Hi Sergio,

I modified the class that is failing..


active_scaffold (ccfc9d71d522) 
lib/active_scaffold/extensions/action_controller_rendering.rb:19:in `render'



@column was nil, so I put in a setter.



I have defined all the columns in the travels controller I could think of, see 
below.



Not sure why it is trying to render “id”. Any other ideas?

# wrap the action rendering for ActiveScaffold controllers
module ActiveScaffold

    def render(*args, &block)
      puts "@@@@@@@ DCB @@@@@ #{params}"
      @column = active_scaffold_config.columns[params[:child_association]]
      puts "@column.inspect #{@column.inspect}<mailto:#{@column.inspect}>"

Hi

The line setting @column is in actions/subform.rb, in do_edit_associated:

@column = active_scaffold_config.columns[params[:child_association]]

What's the value of child_association param in the request? Is that column
included in conf.columns?

Regards
