Responder dosen't care params[:format]

I get xml output when I visit http://localhost:3000/users with following code. I am using rails master.

class UsersController < ApplicationController
  before_filter :detect_browser
  def detect_browser
    params[:format] = 'xml'
  end

  def index
    @users = User.all
    respond_to do |format|
      format.html # index.html.erb
      format.xml  { render :xml => @users }
    end
  end
end

Could it be that if condition is not working in your case?

but I use new responder syntax in rails 3

class UsersController < ApplicationController
  respond_to :html, :mobile
  
  def index
    @users = User.all
    respond_with(@users)
  end
end

it dosen't work with rails master

It's working for me with following code

class UsersController < ApplicationController

  respond_to :html, :xml

  before_filter :detect_browser

  def detect_browser
    params[:format] = 'xml'
  end

  def index
    @users = User.all
  end

end

I see index.html.erb if I comment out filter. With filter on I see index.xml.erb while visiting /users .

It won't work, my log output

this from beta3

======================================
params[:format] = xml
======================================
Processing by UsersController#index as XML

this from rails master

 Processing by UsersController#index as HTML
======================================
params[:format] = xml
======================================

It just processes before params[:format]

Please try to add a failing test case in Rails test suite.
