Trouble with routes in Rails 2.0

Hi,

  I has a nested restful route in routes.rb, which works nicely with
1.2.6:

  map.resources :checklists, :member => {
        :invite => :post,
        :accept => :any,
  } do |checklists|
      checklists.resources :tasks, :member =>
          {
            :invalidate => :any,
            :close => :any,
            :reopen => :any,
            :reorder => :any,

            :collapse => :any,
            :expand => :any,
          }
  end

  For such a definition, i used path like

   tasks_path(checklist_id)

  After upgrade to Rails 2.0, I'm getting the error message:

  undefined method `tasks_path' for #<ActionView::Base:0x69090b0>

  Has no idea where to look at how to fix the problem. rake routes
doesn't show generated paths.

  Any help?

  Regards,
  KIR

Answering myself.
There are two solutions I found:

1. Replace tasks_path with checklist_tasks_path
2. Rewrite routing like:

  map.resources :checklists, :member => {
        :invite => :post,
        :accept => :any,
  }
  map.resources :tasks, :path_prefix => '/
checklists/:checklist_id', :member => {
            :invalidate => :any,
            :close => :any,
            :reopen => :any,
            :reorder => :any,

            :collapse => :any,
            :expand => :any,
     }
