Endless (> 15min) loop with large amount of columns and nested scaffold

[clst]

Hi,

I have a nasty problem: A very large and ugly legacy table:

class Kalkbeschreib < ActiveRecord::Base
  set_primary_key 'Nummer'
  set_table_name 'kalkbeschreib'
end

an embedded scaffold:

#view:
= render :active_scaffold => "user_clock_hlp/kalkbeschreibs"
#controller
class UserClockHlp::KalkbeschreibsController < ApplicationController

  active_scaffold :kalkbeschreib do |config|
    config.create.link=false
    config.show.link=false
    config.update.link=false
    config.delete.link=false

    config.columns = [:KalkNummer, :Pos, :Menge, :Text]

    config.list.sorting = [{:KalkNummer => :desc}, {:Pos => :asc}]

  end

calling the controller like this: /user_clock_hlp/kalkbeschreibs works fine. But when I want to embed the scaffold in the view it hangs the whole rails server and I have to "kill -kill" it as CTRL-C won't work anymore.

Embedding some other scaffold in the same view works fine though.

It is very strange. Can somebody please give some thoughts, I am at a loss.

If you have this problem with master branch, reopen and post your table structure. If this error only happen with that table I will need the table to test it
