Detect if user has "read" an article with Open Graph

Question

Okay so I read this post "http://facebook.stackoverflow.com/questions/10373897/deleting-a-previosly-posted-article-with-opengraph-or-check-if-said-article-has" but I'm using the news.reads action type.

So on the website when a user logs in with Facebook, and grant publishing permissions, every post they read gets pushed to their timeline. Everything is fine until they refresh/revisit the same article where facebook.php emits a Fatal error: Uncaught OAuthException: (#3501) User is already associated to the article object on a unique action type Read. Original Action ID: XXXXXXXXXXXXXXXX

I am fine that there is a bug with the built in news.reads OG and it being unique, but I was wondering if there was away to detect if a user has already read/viewed it.

Something like:

if (user is logged in [$user]) {
    if (user hasn't read article) {
        $facebook->api(/me......);
    } else if (user has read the article) {
        // Do Nothing
    }
} else { // If not logged in
    echo "login";
}

Hopefully that's possible, otherwise it would be a total bummer that I/user cannot view a page a second time without the facebook.php stopping the rest of the page being processed (its before the <html> tag).

Note: I prefer the PHP SDK, but am willing to use JS.

You should have stored the info that user foo has read article bar in your database anyway – since approval requirements for read action demand that you provide the user with an easy way to unpublish this action again.

You don't happen to have some code, or example that I could understand? All the built-in OG is not clear to me, compared to the custom (cookie tutorial/coffee store tutorial/etc.). Even documentation that would let me know about *foo* – markb Jun 15 '12 at 12:11
