I want to create a sortable_element which doesn't send an AJAX
request onUpdate.
However, if the :url option is not included, then rails returns
an error:
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.[]

load' -e:2
The solution I've found is to change like 144 of
scriptaculous_helper from:
options[:onUpdate] ||= "function(){" + remote_function(options)
+ "}"
to
options[:onUpdate] ||= "function(){" + remote_function(options)
+ "}" unless options[:url].nil?
But I don't know if this will fix the problem in all cases.
