UPDATE

Like @sly7_7 said in your answer below, this feature is now avaliable in ember-data. So if you are using the 1.0.0-beta.11 version or greater, this code isn't needed

You can reopen the ManyArray, and create a new method called reloadLinks(). With the following:

var get = Ember.get;

DS.ManyArray.reopen({
    reloadLinks: function() {
        var records = get(this, 'content'),
        store = get(this, 'store'),
        owner = get(this, 'owner'),
        type = get(this, 'type'),
        name = get(this, 'name'),
        resolver = Ember.RSVP.defer();

        var meta = owner.constructor.metaForProperty(name);
        meta.type = type;
        var link = owner._data.links[meta.key];
        store.findHasMany(owner, link, meta, resolver);
    }
});

The usage is the following:

comments.reloadLinks();
