Yahoo YUI 2 - Rich Text Editor - can't get setEditorHTML method to work, what's wrong?
Today, for the first time, I came across the YUI 2 Rich Text Editor. (http://developer.yahoo.com/yui/editor/)
I mainly use Java Server Pages for my websites.
I want to be able to set the text in the textarea of the Editor to a previously submitted value. As an example, when a user submits the page, after having entered text in the Editor, that text may be saved in a database for future use. I would then call the value from the database, and set the Editor to display it at that point, so the user could make modifications.
I found a method in the API documentation called setEditorHTML() - but for some reason or another, I can't get it to work.
Here is the test code I've been playing around with. I'm testing in Firefox.
I don't understand why the setEditorHTML method won't work...can someone please assist me?

There is a time while the editor is rendering which you cannot access setEditorHTML. Try this:
var myEditor = new YAHOO.widget.Editor('msgpost', {
height: '300px',
width: '522px',
dompath: false, //Turns on the bar at the bottom
animate: false, //Animates the opening, closing and moving of Editor windows
handleSubmit: true
});
myEditor.render();
// I just took a guess on which event to use here
myEditor.on('windowRender', function() {
myEditor.setEditorHTML("Hello World");
});
Here is a list of YUI Editor events.
