Error Handling on Ajax pages

Hi,

I'm having a problem with displaying errors on an Ajax page.
On the page users can upload images and when an image is uploaded it
will be added to the list of already uploaded images using

page.insert_html :bottom, "assets", :partial => 'assets/
list_item', :object => asset

The problem is that I don't really know how to display error messages
that occurred while uploading images (i.e. file to large, wrong
content type)

What I did right now is insert this in my controller

      if @asset.save
        .......
      else
          format.js do
          responds_to_parent do
            render :update do |page|
              @asset.errors.each do |e|
                  page.notify :error, e[0]+" "+e[1]
              end
            end
          end
        end

page.notify will then display the error message at the top of the
page.

While this is working I would think that there's gotta be a prettier
way of doing this. Is there?

Marc

I'm using the:
page.replace_html :some_your_error_div_id, error_messages_for(:image)
