[playlist], [audio] and [video] via AJAX don't work in 4.0-beta2 (but work in 3.9.1)

[Looimaster]

In WordPress 3.9.1 I was able to get playlist/audio/video output via AJAX (with do_shortcode()) and initialize it like that:

jQuery('.wp-playlist').each(function(){
	return new WPPlaylistView({ el: this });
});

With [audio] and [video] I called $(this).mediaelementplayer(); instead.

Here's the execution flow copied from Chrome's Console (4.0-beta2-20140723):

Uncaught TypeError: Cannot read property 'replace' of undefined underscore.min.js?ver=1.6.0:1

Moving to 4.0 for investigation.

I have no idea what custom code you are calling, where, or how, but the shortcodes work as expected as for me.

If you can edit the shortcodes in the modal, "AJAX" works just fine.

The full code I'm using is above. It's only three lines. I do do_shortcode('[playlist]'); and run new WPPlaylistView({ el: this }); where this is the returned container with .wp-playlist class. This error still happens in 4.0-beta3-20140812. It does not happen in 3.9.1. I can load playlist with AJAX on the front-end and setup it with the above code.

and the plugin that does this has the same code.

Can you please share the plugin public?

I tried that prepare a reduced test case and I got this error: Uncaught ReferenceError: WPPlaylistView is not defined instead of the error I mentioned earlier. I just found wp_playlist_scripts('audio'); and wp_playlist_scripts('video'); and when I add that to the plugin it starts working in 4.0-beta3 too. In 3.9.1 it works without these two functions.

So, this ticket can be closed. It's resolved.
