Facebook comments_info FQL table returning null on my app_ID

I'm doing this facebook comments for a friend and I can't get any info with FQL nor with graph api... I need to make him a table of all the comments with likes and so on. I want to use FQL but trying with Graph API to see info didn't work either.

My situation is kinda complicated...

The HTML/JS for the comments runs on my server, but people use it inside a facebook page IFRAME for another app ( I switched app ID's somewhere in the middle, I only found that out now... :| ), so the comments href point to a somewhere that has the second app id in it...

This is what important inside it's code (if it's something else, tell me and I'll post it):

/* APP ID replaced with X, URL replaced with Y */

<meta property="fb:app_id" content="X">

.....

<script src="http://connect.facebook.net/en_US/all.js#appId=X&amp;xfbml=1">
</script>

....

<script>

FB.init({

appId  : 'X',

status : true,

cookie : true,

xfbml  : true 

});

</script>

.....

<fb:comments href="Y" numposts="10" width="490" publish_feed="true"></fb:comments>

So , I tried retrieving info with: https://graph.facebook.com/comments/?ids=Y// Returns empty data https://graph.facebook.com/comments/?ids={place on my server} // same thing

I tried FQL:

SELECT app_id, xid, count, updated_time FROM comments_info WHERE app_id="X" //returns null

and

SELECT app_id, xid, count, updated_time FROM comments_info WHERE app_id="{APP Id of IFRAME}" // returns em开发者_开发技巧pty data

Ok, I find out why this happened, since the Y url is part of facebook, it doesn't belong to my app thous not allowing me to access information...

Sorry for taking so much time to post this, but I forgot I asked this... anyway - facebook comments is no fun ....
