Hey everybody,

I am trying to code a small application in FB in order to learn how to  
do it with RoR, but I run into the following problem once I already can  
connect to my application:

Swapping facebooker config: ‘d1591b2c19797dcd182e8232c75ee662’  
e[4;36;1mSQL (2.0ms)e[0m e[0;1mSET NAMES 'utf8’e[0m  
e[4;35;1mSQL (3.0ms)e[0m e[0mSET SQL\_AUTO\_IS\_NULL=0e[0m

Processing MainController#index (for 69.63.190.246 at 2010-08-06  
15:41:54) [GET]  
Parameters: {“fb\_sig\_in\_canvas”=\>“1”, “fb\_sig\_request\_method”=\>“GET”,  
“fb\_sig\_locale”=\>“en\_US”, “fb\_sig\_in\_new\_facebook”=\>“1”,  
“fb\_sig\_time”=\>“1281102112.3388”, “fb\_sig\_added”=\>“0”,  
“fb\_sig\_country”=\>“es”, “fb\_sig\_api\_key”=\>“…”, “fb\_sig\_app\_id”=\>“…”,  
“fb\_sig”=\>“…”}

ActionController::UnknownAction (No action responded to index. Actions:  
create\_facebook\_session, create\_facebook\_session\_with\_secret,  
facebook\_params, facebook\_session, facebook\_session\_parameters,  
one\_or\_true, redirect\_to, render\_publisher\_error,

start\_thread’

Rendering  
D:/Projects/gorrillas/vendor/plugins/facebooker/templates/layout.erb  
(200)

I am not really sure of what it could be, but if I point my browser to  
[http://localhost:3000/](http://localhost:3000/) I can see a rendered text I wrote in order to  
know whether the app was running fine or not, but once I go to my app’s  
facebook page, I get the ActionController::UnknownAction error…

Thanks a lot in advance!
