I'm learning Rails and went through the flickr tutorial screencast at: http://media.rubyonrails.org/video/flickr-rails-ajax.mov
Couldn't get it to work with Rails 2.0 in Aptana, so made these changes to index.rhtml and am posting them in case they are useful to someone else.
<% form_remote_tag :url => {:action => 'search'}, :update => 'photos', :complete => visual_effect(:blind_down, 'photos'), :before => %(Element.show('spinner')), :success => %(Element.hide('spinner')) do -%>
<%= image_tag('spinner.gif', :id => 'spinner', :style => 'display: none') %>
Seems to be working, hope this is the "correct" way.

P.S. seems like many tutorials (all of those on http://www.rubyonrails.org/docs???) are for pre-2.0 and don't work. Anybody have pointers to newer tutorials? same problem with books - have a couple of $50 doorstops...
