Can't get flash to update between remote calls

Hi,

I'm trying to send information between AJAX calls using flash but the
hash only seems to be updated the first time I run it.

This is the method being called remotely using a remote_form_tag:
  def authenticate
    @user = User.find_by_email(params[:email])
    if @user.nil?
      flash.now[:email] = "UserLoginErrEmailNotFound"
      render( :partial => "login_form" )
    elsif @user.password != params[:password]
      flash.now[:password] = "UserLoginErrInvalidPassword"
      render( :partial => "login_form" )
    else
      session[:id] = @user.id
      session[:locale] = @user.locale
      redirect_to :controller => "welcome", :action => "index"
    end
  end

The first time I call it I enter a invalid email and get the following
debug:
--- !map:ActionController::Flash::FlashHash
:email: UserLoginErrEmailNotFound

If I enter a valid email, that is found in the database I should
receive invalid password in the flash but I get this when debuging in
the view:
--- !map:ActionController::Flash::FlashHash
:email: UserLoginErrEmailNotFound

Why hasn't the flash changed in the view? I've added logger statements
to the controller to make sure the flash contain the correct values.
Any clues!?

Kind regards,
Roland

Finally the solution to my problem!

The render(:partial... call above is missing a :locals parameter
telling which div to updated.

Anyways, my problem is solved.

Kind regards,
