I did the same thing with my app

Also, my post-add url hits a controller protected by the ensure installed

same thing here - my app in post add (even though my app fails during the
add)  works perfectly fine

I'm assuming your callback url calls an 'add' method for your app
besides saving facebook uids - does it do anything like app redirection?

For some reason, I don't know why - facebooker things the actual signature
during an application add, is my app's secret key - when it's supposed to be
blank...

it was the 1st thing I read... but in my case I need to see the whole
