setupChildIframe cannot find childIframe

[David A. Jafari]

I'm setting up a new container and just tried loading my first gadget. The 
metadata response comes back from the server successfully, but then the 
setupChildIframe function is called trying to locate an iframe with which to 
load the gadget. I've not manually created such a frame nor do I see others 
creating one in the examples. Here's what I'm doing:

Import of container dependencies:

<script 
src=".../gadgets/js/core:pubsub:container:rpc.js?container=default&c=1&debug=1"></script>

Create container and set security token:

var CommonContainer = new osapi.container.Container(testConfig);
shindig.auth.updateSecurityToken(mySecurityToken);

Load a gadget by Gadget Spec url:

var site = this.commonContainer.newGadgetSite(gadgetNode);
this.commonContainer.navigateGadget(
          site,
          url,
          { view: "home" }, //view parameters
          { }, //render parameters
          callback
      );

Am I missing a step somewhere? My basic goal here is simply to load a gadget 
into the page through our local rendering server.
