Hi,

I have been using rails to talk to sproutcore. I did exactly what the  
tutorial talks about. Also I downloaded the sproutcore-examples as  
instructed in the tutorial. Now when I run the local host :  
[http://localhost:4020/contacts](http://localhost:4020/contacts) I do not get records listed on the left  
pane, instead I get a message on the console as below:

REQUEST: get /sc/contacts/list  
GET [http://localhost:4020/sc/contacts/list?order=id](http://localhost:4020/sc/contacts/list?order=id)

I understand the get request is posted at  
[http://localhost:4020/sc/contacts/list?order=id](http://localhost:4020/sc/contacts/list?order=id)  
When I looked the above URL, below is the message I get. Could someone  
please help me to see where I could be going wrong ??? I have also  
posted this a few days ago.
