There's a known issue with the TinyMCE class used in wp_editor(); that it can't be moved around in the DOM: http://codex.wordpress.org/Function_Reference/wp_editor#Notes

So I'm thinking that this approach will not work well if you're trying to use an Ajax-enabled Gravity Form.

I haven't tested it or played around with it, but the only fix I could imagine would be somehow registering a javascript handler on the "gform_page_loaded" hook that calls whatever functions are needed to initialize the tinymce editor. tinyMCE.init() would be a good place to start, but I think there might be more function calls necessary to fully initialize an editor.

i paste your code in my function. but now i don't see any editor add any text editor

This doesn't seem to save any formatting within the WYSIWYG. It's all stripped on submitting.

Rad! Code largely works on current Gravity Forms, I have run into an issue with pasted text:

I can include rich text if I manually type out content into the post content field, however if I paste in content directly, it looks fine and is formatted properly before submitting the form, but the output results in completely blank content (not just no styles, no content at all). I can then go in the admin area and edit the post, no content in the post body.

Anyone have any idea what might be stripping cut and pastes like that? Thanks!

Hello,
I would change the test with the following:
if( $field["useRichTextEditor"] == '1' ) {
