title: tinymce won't get (id) or setcontent
body: <p>Here is my code that I'm using. I'm trying to get tinymce to load existing data into the TEXTAREA, but nothing I've tried so for, nor any "solutions" I've so far located have worked. The editor loads fine, as long as I don't try to load data:</p>
  
  <pre><code>&lt;script type="text/javascript" src="http://URL/scripts/tinymce/js/tinymce/tinymce.min.js"&gt;&lt;/script&gt;
  &lt;script type="text/javascript"&gt;
  tinymce.PluginManager.load("spellchecker","http://URL/scripts/tinymce/js/tinymce/plugins/spellchecker/plugin.min.js");
  tinymce.PluginManager.load("wordcount","http://URL/scripts/tinymce/js/tinymce/plugins/wordcount/plugin.min.js");
  tinymce.init({
    selector: "textarea#my_id",   
    theme: "modern",
    plugins: [
      "advlist autolink lists link image charmap print preview hr anchor pagebreak",
      "searchreplace wordcount visualblocks visualchars ",
      "insertdatetime media nonbreaking save table contextmenu directionality",
      "template paste textcolor spellchecker code"
    ],
    relative_urls : true,
    document_base_url : "http://URL/",  
    content_css: "scripts/tinymce/js/tinymce/skinslightgray/skin.min.css",
    external_image_list_url : "tinymce_imagelist.js",
    toolbar: "insertfile undo redo | styleselect | bold italic | alignleft aligncenter alignright alignjustify | bullist numlist outdent indent | link image media | print preview | forecolor backcolor",
    autosave_ask_before_unload: false
  });
  tinyMCE.activeEditor.setContent("textarea content in here");      // &lt;-- this doesn't work
  &lt;/script&gt;
  &lt;textarea name="Blog_Text" id="my_id" class="editable" cols="60%" rows="20"&gt;&lt;/textarea&gt;
  </code></pre>
  
  <p>I've tried:</p>
  
  <pre><code>tinyMCE.activeEditor.setContent("textarea content in here");
  tinyMCE.get("my_id").setContent("textarea content in here");
  
  var ed = tinyMCE.getInstanceById("blog_text");
  ed.focus();
  ed.setContent("textarea content here");
  
  $('#my_id').html("textarea content here");
  </code></pre>
  
  <p>If I don't try to load the textarea id then the editor loads correctly (without the content).</p>
  
  <p>I've searched for the solution, but NOTHING is working. I really need the solution for this one. I've tried putting the line before the "init" as well as after. </p>
  
  <p>I do wish that examples would be shown in context, just a line doesn't help with a tool as complex and unforgiving as tinymce.</p>
