Hi!

In my view i have remote_form_for and action in controller:

def save_offer_basics     @offer = Offer.new params[:offer_basics]     @offer.user_id = current_user.id     @offer.enable_validation_group :offer_basic

    render :update do |page|       if @offer.valid?        @offer.save         flash[:notice] = 'Podstawowe dane oferty zostały zapisane! Kolejnym krokiem jest wybranie kategorii.'         page[:mdiv].replace_html message_block(:on => [:offer])         page[:offer_basics_id].value = @offer.id       else        page[:mdiv].replace_html message_block(:on => [:offer])       end       page[:mdiv].show     end   end

Unfortunetly it never saves. When i debug code with netbeans it stops on line render :update do |page| with exception:

undefined method `class_eval' for #<ActionView::Helpers::PrototypeHelper::JavaScriptGenerator: 0xb5f0165c>

with trace

Thanks for any help :slight_smile:

This is some of your code (or a plugin you have installed). It's been evaluated in the context of the javascript generator class and you to be careful in there because most methods that exist are undefined in there.
