title: dojo 1.7 dojox/form/Uploader not displaying the file picker dialog
body: <p>My end game is to add the uploader to a dialog. That was not working so I went the simple route to see if it would work. Below is as about as simple as I can go and sadly the file picker does not display when the button is clicked. I am working in Firefox and Chrome. If anyone would be kind enough to look this over and find a goof I would appreciate it.</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false">
  <div class="snippet-code">
  <pre class="snippet-code-js lang-js prettyprint-override"><code>require(["dojox/form/Uploader",
      "dojo/dom",
      "dojox/form/uploader/plugins/IFrame",

    ],
    function(Uploader, dom) {
      var u = new Uploader({
        name: "myPhoto",
        label: "Upload Your Photo",
        multiple: false,
        uploadOnSelect: true,

      dom.byId("myDiv").appendChild(u.domNode);
