Sort Helper2 for column header sorting

I’ve been using SortHelper2 (http://wiki.rubyonrails.org/rails/pages/
SortHelper2) to help with column header sorting in a table. The
problem is, it only seems to work in the LIST action/view for any
controller. I want to use the sorting helpers in my search_results
view page. When I try to add it there, I get errors:

The error occurred while evaluating nil.[]
#{RAILS_ROOT}/app/helpers/sort_helper.rb:53:in `sort_link’

It looks like the “/list” part of the URL is hardcoded in somewhere,
when building the link in the “sort_link” function. How can I change
this, and if I do change this to say “search_results”, will it even
work?

Any suggestions appreciated!!
