Rails - Mar 2009 - render layout not working for application.xml.builder

I have layouts/application.xml.builder which is rendered for all xml
reponses.
In controllers I have:

format.xml { render :layout => true, :xml => @some_var }

This works perfectly fine in rails 2.1.2 and stopped working after upgrading
to 2.2.2.
It appears that :layout => true is not taking any effect.  The
@some_var.to_xml is rendered just not with
application.xl.builder any more.  I googled around and tried a bunch of
different approaches but
stuck.  Anyone seen something like this?

Thanks,

''application''?

Heinz,

Yes I have.  I wrote a tiny app to illustrate my problem.

I have one model - user.rb:
class User < ActiveRecord::Base
  def name
    "foo"
  end
end

and users_controller.rb:
class UsersController < ApplicationController
  def index
    respond_to do |format|
      format.html
      format.xml do
        render :xml => User.new, :layout =>
''application''
      end
    end
  end
end

I defined routes for it:   map.resources :users

Then I change this to vary rails'' versions for testing:
RAILS_GEM_VERSION = ''2.2.2'' unless defined? RAILS_GEM_VERSION

Using :layout => ''application'' or not doesn''t
matter.  When I hit
http://localhost:3000/users.xml
I get this output:

Processing UsersController#index to xml (for 127.0.0.1 at 2009-03-16
17:41:10) [GET]
  [4;36;1mSQL (0.3ms)   [0;1mSET SQL_AUTO_IS_NULL=0
  [4;35;1mUser Columns (1.5ms)   SHOW FIELDS FROM `users`
Rendering template within layouts/application
Completed in 34ms (View: 6, DB: 2) | 200 OK [http://localhost/
users.xml]

As you can see, it is renderin layouts/application.

I have defined views/layouts/application.xml.builder as such:
xml.instruct!

xml.response do
    xml << yield
end

And what I get is:
-
<user>
<created-at type="datetime" nil="true"/>
<updated-at type="datetime" nil="true"/>
</user>

What I expect to get is xml instruct on top,
then a response node, with user inside.

Any more insight will be greatly appreciated.

Zhao
