Facebooker talk - Dec 2008 - parameter passing before install lost after install???

I was wondering if anyone else is having problems with passing query string
parameters upon install.  For example, in the book Developing Facebook
Platform Applications with Rails, the books example adds params[:from_id]
into an invitation, so when another person signs up from the invitation, you
can track who invited who.  And that would make your friend in your dojo.  I
was using something like this before and eveything was working fine, but now
it seems like it is not working anymore.  Is anyone having similar
problems?  Is this something facebook does not allow anymore?

Your feedback is very helpful.

I think this changed in recent versions of the platform. If you set up  
a post authorize redirect URL, you can use the next parameter to keep  
parameters. You can see how I do this in the screencasts on
http://www.pragprog.com
. The code is in the facebooker_authentication plugin on github.

I think I found out why its not working.  I was using
"ensure_application_is_installed_by_facebook_user" and my logs were
saying
"Filter chain halted as [:ensure_application_is_installed_by_facebook_user]
rendered_or_redirected."

Because I am using facebooker_authentication, I am using the before_filter
:facebook_login_required.  I also wanted to make sure that the application
is installed by the facebook user in order for them to access my app.  How
could I use ensure_application_is_instaled_by_facebook_user without losing
the parameters on install?  Is there a fix that could be incorporated into
facebooker that would allow for parameter passing with this before_filter?
If I understand correctly, facebook_login_required only makes sure that a
user is logged into facebook, not that the user has the application
installed.  I would like to make sure that the user has the application
installed as well.

Best

Here was my fiter chain that was making my parameters disappear.

ensure_application_is_installed_by_facebook_user :except =>
''tab''
before_filter :facebook_login_required, :except => "tab"

Now if I reverse them:
before_filter :facebook_login_required, :except => "tab"
ensure_application_is_installed_by_facebook_user :except =>
''tab''

Things work are working again.  Is there a reason for this?
