Why is this collection empty? (Collection.find() is successful om server)

Ok this is what I've got. The collection called Posts has content and I want to publish this under the name Merchs, the find() in the publish-function finds data but that is not shared to the client where Merchs is always empty.

//shared

Merchs = new Meteor.Collection('merchs');
// Posts has data I want to publish as "Merchs"
this.Posts = new Meteor.Collection('posts');

//server 

Merchs.allow({
  insert: function(userId, doc) {
    return true;
  },
  update: function(userId, doc, fields, modifier) {
    return true;
  },
  remove: function(userId, doc) {
    return true;
  }
});

Meteor.publish('merchs', function(data) {
    return Posts.find();
});

//client 

Deps.autorun( function() {
    Session.get('selectedCategories');
    subs.subscribe('merchs');
});

When creating your collection, the name in parentheses should be the name of the Mongo collection.

Merchs = new Meteor.Collection('merchs');

Should be:

Merchs = new Mongo.Collection('Posts');

That is, unless you already have a Posts variable defined in code that you didn't show. If you've already defined Posts and you're just looking to make another subscription to the same collection then you don't need this line at all:

Merchs = new Meteor.Collection('merchs');

You also don't need your allow() method (you can just use the one defined for Posts). All you need is the publish() method that you defined.

On the client side you also need:

Meteor.subscribe('merchs');

Also note the use of Mongo.Collection instead of Meteor.Collection which was renamed in Meteor 0.9.1.
