Rails - Mar 2006 - Controller instance variables falling in and out of scope

Very bizarre behavior has cropped up in a few spots.

# the action for viewing a blog post
def posts
  @post = BlogPost.find_by_slug(params[:id], :include => :commentary)
  # a breakpoint here shows @post and @post.commentary with appropriate data
  redirect_to :action => ''archive'' unless @post
end

# posts.rhtml
<%= @post.inspect %> => nil
<%= render :partial => ''post'', :object => @post %>
=> renders with correct data
<%= @post.comments %> => NoMethodError
<%= render_tree_of( @post.comments, ... ) %> => generates no errors,
but within the partial reports @post.comments as nil

WinXP
Ruby 1.8.2
Edge Rails (behavior has existed over several iterations now)

I''ve not run into anybody else with this problem, and have not had
much luck with IRC and my own debugging efforts. Any clues?

I should probably add that BlogPost#comments is defined to return a
mapped version of BlogPost#commentary.

Turns out it was a filter in ApplicationController calling
render_to_string... interesting behavior nonetheless.
