TinyMCE Unable to get property 'setContent' of undefined or null reference
Question
I know this topic has been covered many times here but no matter which approach I take I either get a error such as "Unable to get property 'setContent' of undefined or null reference" or the line executes but nothing happens.
Here's what I know. tinymce initializes and is a valid object. The html variable has the propper HTML which it get from a parent window. jQuery is loaded and functional.
In addition to the code below I have also tried.
tinyMCE.activeEditor.setContent(html);
tinymce.editors[0].setContent(html);
$('textarea#XRMeditor').val(html); * Before initialization
I have tried all methods before and after tinymce intializes (just in case).
<!DOCTYPE html>
<html>
<head>
<script src="sage_jquery.min.js" type="text/javascript"></script>
<script src="tinymce_/tinymce.min.js" type="text/javascript"></script>
<script>
var html = window.parent.document.getElementById("descriptionIFrame").contentDocument.getElementsByTagName('body')[0].innerHTML;
debugger;
//$('textarea#XRMeditor').val(html);
tinymce.init({
selector: 'textarea#XRMeditor'
});
tinymce.get('XRMeditor').setContent(html);
</script>
</head>
<body>
<textarea id="XRMeditor">Easy (and free!) You should check out our premium features.</textarea>
</body>
</html>

I suspect this issue is that you are trying to talk to TinyMCE before its initialized on the page.
Your get() call is in the head of your page and I would doubt that when the browser processes your script that TinyMCE has initialized. You can use an "init" handler to delay when this call happens:
tinyMCE.init({
//your regular init parameters here...
setup: function(editor) {
editor.on('init', function() {
//load your content here!
tinymce.activeEditor.setContent(html);
//or
tinymce.editors[0].setContent(html);
});
}
});
