Strange change in form_tag behavior from 2.0 to 2.1?

I've used an approach frequently in the past where I create a method in the model that when passed parameters from a selection form returns a modified result set. As an example the routine in the model looks like this;

  def self.find_by_search(params) (shortened for easy reading)     where =     unless params[:agency].blank?       where << "agency_id = :agency"     end     if where.empty?       find(:all,            :order => params[:order])     else       find(:all,            :conditions => [where.join(" AND "), params],            :order => params[:order])     end   end

Then the controller uses this model/method to modify the result set based on the user's entries.

  def ecase_search     @title = "Search Cases"     return if params[:commit].nil?       @ecase = @account.ecases.find_by_search(params)       @ecases = @ecase.paginate :per_page => 8,                                  :page => params[:page]     render(:template => "evidence/ecases/index")   end

The search form that is supposed to pass the params back to the controller action looks like this;

<% form_tag( ecase_search_path, :method => "get") do %> (shortened for easier reading)   <div id="search" class="box" <%= 'style="display:none;"' %> >     <table>       <thead>         <tr>           <th><%= "Search Field" %></th>           <th><%= "Search Value" %></th>         </tr>       </thead>       <tbody>         <tr>           <td><strong><%= "Agency Code" %></strong></td>           <% @agencies = @account.agencies.find(:all) %>           <% @agencies << @account.agencies.new(:id => '', :description => 'All') %>           <td><%= select_tag(:agency, options_for_select(@agencies.collect { |c| [ c.description, c.id ] }), :style => "width:150px", :id => :indexselect) %></td>         </tr>         <tr>           <% @selections = %w(agency_id incident_id officer evidences_count) %>           <td><strong><%= "Order By" %></strong></td>           <td><%= select_tag(:order, options_for_select(@selections), :style => "width:150px", :id => :indexselect) %></td>         </tr>         <tr>           <td><%= submit_tag "Find Results", :class => "submit" %></

          <td colspan="1"></td>         </tr>       </tbody>     </table>   </div> <% end %>

The routing in routes.rb looks like this;

map.ecase_search 'ecase_search', :controller => 'evidence/ ecases', :action => 'ecase_search'

The error I get when I try this approach is;

ActionController::MethodNotAllowed Only get, head, post, put, and delete requests are allowed.

This approach worked wonderfully in 2.0 but now fails in 2.1. I had a similar problem in 2.1 when I found that nested tables had to be called differently in the form_for such as (<% form_for([@account, @agency]) do |form| % ) Any thoughts are greatly appreciated. Kathleen

You know what it was??? The route somehow was not high enough up in the routes.rb file? I have no idea why this is as there's not another route like this..but I just thought I might make someone's day a little easier. Kathleen
