And if you have more than one instance of the editor running you may want to use the triggerSave() method:

[tinymce.com...]

If you want to focus on any element after realizing it is empty you can use the execCommand:

[tinymce.com...]
[tinymce.com...]

pseudocode example:

if (your textarea has an error) { 
  tinyMCE.execCommand('mceFocus', false, 'textareaID'); 
  return false; 
}
