Somehow missed the comment notification and been wrapped up in other stuff. No, you don't need to parse the XML, it's automatically parsed by XMLSImple into a hash, with the object types as keys, e.g "members".

I presume I need to parse the XML I get back from the call to get the UIDs? I'm using your library to power a Merb application rather than a Rails one. Thanks for writing this piece of code.

The app I initially wrote it for is Autopendium (http://autopendium.com) which is mainly outside of Facebook. It's partly why I needed a more flexible library, because the existing ones assumed that you lived wholly within Facebook.

Fair enough. In fact, it's encouraged me to make my app live entirely within FB, and use some of their mock AJaX. If you want to see it in action, it's at http://apps.facebook.com/gimmmee/, and I couldn't have built it without you. Thanks again, Lenny Hi Chris,

I've set up a basic hello world app using an iframe and I'm unable to reproduce the errors. Here's how I've got the app set up so you can see how your basic setup differs. -- Basic rails app. -- Single controller (DummyController): class DummyController < ApplicationController def index @user = facebook.user end end The index template is a single line: Hello -- ApplicationController includes Facebook controller methods: class ApplicationController < ActionController::Base include FacebookUtilities::ControllerUtilities end The Facebook application (ct_qwiktest) is set up to use an iframe: Callback Url: http://localhost:3000/dummy and the index action is accessed via this URL: http://apps.facebook.com/ct_qwiktest/ If I add a filter to the dummy controller: before_filter :require_logged_in_to_fb_app it redirects me to to app's login page. Agreeing to login then allows the index page to render Hello XXXXX where XXXX is my facebook uid. If I change the filter to be :require_added_fb_app instead I get redirect to a page asking me if I want to add the application with a series of check boxes to specify what it should be able to do (i.e. permissions). I don't get into the whole auth_token stuff because at all times I'm staying within the Facebook frame (whether iframe or canvas). I only need the auth_token for an outside page that isn't render within the confines of the facebook frame -- e.g. if I navigate to http://localhost:3000/dummy Not sure if this helps, but hopefully it will. OK. I’ve set up a basic hello world app using an iframe and I’m unable to reproduce the errors. Here’s how I’ve got the app set up so you can see how your basic setup differs.

– Basic rails app.
– Single controller (DummyController):

class DummyController < ApplicationController
def index
@user = facebook.user
end
end

The index template is a single line:
Hello

– ApplicationController includes Facebook controller methods:

class ApplicationController < ActionController::Base
include FacebookUtilities::ControllerUtilities
end

The Facebook application (ct_qwiktest) is set up to use an iframe:
Callback Url: http://localhost:3000/dummy

and the index action is accessed via this URL:
http://apps.facebook.com/ct_qwiktest/

If I add a filter to the dummy controller:
before_filter :require_logged_in_to_fb_app
it redirects me to to app’s login page. Agreeing to login then allows the index page to render Hello XXXXX where XXXX is my facebook uid.

If I change the filter to be :require_added_fb_app instead I get redirect to a page asking me if I want to add the application with a series of check boxes to specify what it should be able to do (i.e. permissions).

I don’t get into the whole auth_token stuff because at all times I’m staying within the Facebook frame (whether iframe or canvas). I only need the auth_token for an outside page that isn’t render within the confines of the facebook frame — e.g. if I navigate to http://localhost:3000/dummy

Not sure if this helps, but hopefully it will.
