Rails - Sep 2007 - undefined method `request' for "products":String ?

Since updated edge yesturday i have had a series of errors related to
undefinded methods for "products":String.

I do have these controllers namespaced.


===Errors example 1:
undefined method `request'' for "products":String
Extracted source (around line #2):


view:
    <tbody>
        <%= render :partial => ''admin/products/product'',
:collection =>
@collection %>
    </tbody>


view parital
_product

1: <tr id="<%= dom_id(product) %>" class="<%=
cycle(''odd'', ''even'') %>">
ERROR HERE> 2:   <td><%= image_tag( product.cover(:thumb_50), :class
=>
''image'' ) if product.cover(:thumb_50)  %></td>


model:
class Product ...
.
.
    def cover(size)
      assets.blank? ? nil : assets.first.public_filename(size)
    end


==Errors example 2:
undefined method `url_for'' for "categories":String
Extracted source (around line #10):

7:     <thead>
8:       <tr>
9:         <th width="30">&nbsp;</th>
10:>>>         <th width="auto"

  def link_to_orderable(name, order, default = false)

    case params[:order]
      when default && nil
        className = "ordered_desc"

      when order
        className = "ordered"
        order = "#{order} desc"

      when "#{order} desc"
        className = "ordered_desc"
    end

    options = params.merge(:order => order, :page => nil )
 >>   link_to(name, options, :class => className)
  end

Seems that link_to uses url_for

Ok so i made a SMRT error the night before.

I created, as a test, an attribute called @controller in my 
base_controller (from which all controllers inherit function).

This causes the errors.

Case closed, i have a bad memory.
