Hi,

just override the default helper.

here's the source (ie put this in your helper, and then change it to
fit)

def error_messages_for(*params)    options = params.extract_options!.symbolize_keys    if object = options.delete(:object)      objects = [object].flatten    else      objects = params.collect {|object_name|
instance_variable_get("@#{object_name}") }.compact    end    count = objects.inject(0) {|sum, object| sum +
object.errors.count }    unless count.zero?      html = {}      [:id, :class].each do |key|        if options.include?(key)          value = options[key]          html[key] = value unless value.blank?        else          html[key] = 'errorExplanation'        end      end      options[:object_name] ||= params.first      options[:header_message] = "#{pluralize(count, 'error')}
prohibited this #{options[:object_name].to_s.gsub('_', ' ')} from
being saved" unless options.include?(:header_message)      options[:message] ||= 'There were problems with the following
fields:' unless options.include?(:message)      error_messages = objects.map {|object|
object.errors.full_messages.map {|msg| content_tag(:li, msg) } }

     contents = ''      contents << content_tag(options[:header_tag] || :h2,
options[:header_message]) unless options[:header_message].blank?      contents << content_tag(:p, options[:message]) unless
options[:message].blank?      contents << content_tag(:ul, error_messages)

     content_tag(:div, contents, html)    else      ''    end end
