title: Tinymce doesn't save the text as it was submitted
body: <p>I have set tinymce in my website so that the user can use the toolbar while writing text as well as to upload a picture. Unfortunately I have realized the problem related to tinymce. </p>

      // Note: In modern browsers input[type="file"] is functional without 
      // even adding it to the DOM, but that might not be the case in some older
      // or quirky browsers like IE, so you might want to add it to the DOM
      // just in case, and visually hide it. And do not forget do remove it
      // once you do not need it anymore.

          // registry. In the next release this part hopefully won't be
          // necessary, as we are looking to handle it internally.
          var id = 'blobid' + (new Date()).getTime();
          var blobCache =  tinymce.activeEditor.editorUpload.blobCache;
          var base64 = reader.result.split(',')[1];
          var blobInfo = blobCache.create(id, file, base64);

  <p>The problem is when a user creates a table or uses any toolbar options (bold, italic, text color or etc.) and submits, in the database the information is received as the user inserted, however if the user wants to edit the info and resubmit, then in the textarea all the words are just displayed without any table or any toolbar features. I would like to have it in a way that the user finds his/her text as it was submitted before if he/she wants to edit the text.</p>
