[Facebooker-talk] facebook_session not working for me

[Dustin Anderson]

Thanks Dave,

I deleted all the content in my session table - didn't seem to change
much, but we'll see.

Anyway, I noticed that when I hit the new action with a value in
params[:from], I get this error in my server log:

Filter chain halted as
[#<ActionController::Filters::ClassMethods::SymbolFilter:0x274f3e0
@filter=:ensure_application_is_installed_by_facebook_user>]
rendered_or_redirected.

Here is what my "invitations/new" action looks like:
  def new
    if params[:from]
      @user = facebook_session.user
      @user.profile_fbml = render_to_string(:partial=>"profile",
:locals=>{:from=>params[:from]})
    end
    @from_user_id = facebook_session.user.to_s
  end

For the record, I don't have +protect_from_forgery :secret+ set to
anything in application_controller.rb

any ideas what I'm doing wrong?

Thanks again for all the help...

Dustin
