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, Roland
