The callback url is correct and I don't see any Javascript errors but I did find out something interesting.

The code that Facebook returns in the url ends in "#=". If I remove this from the end, the page loads.

Well, I thought it was working in the browser as a mobile web app but I just tested and I also get the blank white page after the Facebook redirect.

But this is so very close to working. Facebook authentication works and correctly re-directs back to the correct page of the app. It's just that the page doesn't display/load for some reason. Do you know what the issue is here? There must be a solution to this?

I'm sorry but I don't fully understand how the Generic Service works and how it is used. Where do I define this service? How do I invoke this service? Do I use the mapping UI with this service? How do I map to a list?

Hi Max,

One other related question: I would like to make some modifications to the result set (such as sorting) before mapping the output to a list on the screen. I tried making these changes in the success event but the changes don't get reflected when mapped to the list. Any suggestions?
