How to handle Facebook connection expired

Hi guys,

we're facing the issue of having an expired Facebook token for a user in our DB, so we thought about doing sth. like this:

// refresh FB connection in case of expired access token...
if (facebookConnection.hasExpired())
{
facebookConnection.refresh();
}

But this results in the exception attached below, so our simple question: how can we somehow extend the token???

Cheers, FLorian;
