We're sending out a chunk of json to node/faye and having some issues with nested arrays. Here is the json:

As you can see there are a lot of 'empty' elements (just ""). For the 'top level' object this is fine, we get 'key': ''. But, for the sub array (in this case 'horses') the "" elements are simply removed.
This must be happening on the client side - everything we see on the server side looks ok. Even using static json pulled from a file exhibits the same behaviour on the client.
Are we doing something wrong or is this an issue with node/faye?
If you need to create a placeholder in the array, use NULL instead of an empty string.
