Action Controller: Exception caught
Showing room/search.html.erb where line #9 raised:
You have a nil object when you didn't expect it!
You might have expected an instance of ActiveRecord::Base.
The error occurred while evaluating nil.[]

Hi!
You can find documentation for PrototypeHelper with good examples
here:
http://api.rubyonrails.org/classes/ActionView/Helpers/PrototypeHelper.html
Also, always check your code, maybe even get your hands on a good
development environment:
<%= observe\_field\(:search\_name,:frequency =>
0.25,:ulr=>{:action=>'search_ajax'},:with=>"prefix",:update=>:room)%>
What's an "ulr"?
