Javascript error when integrating django-tinymce and django-filebrowser

I've set up django-filebrowser in my app without any bugs, I already had django-tinymce set up and it loads the editor in the admin forms. I now want to use django-filebrowser with django-tinymce, but I keep getting a weird javascript error when I click on "Image URL" in the Image popup:

r is undefined

the error is js/tiny_mce/tiny_mce.js

My settings.py file has the following configuration:

TINYMCE_JS_URL=MEDIA_URL + 'js/tiny_mce/tiny_mce.js'
TINYMCE_DEFAULT_CONFIG = {
    'mode': "textareas",
    'theme': "advanced",

}

TINYMCE_FILEBROWSER = False
TINYMCE_COMPRESSOR = False

i've tried switching back to older versions of tinyMCE Javascript but nothing seems to work. Would appreciate some help

Figured this out, I just had to place the javascript code for the Custom File Browser in the right place and tweak the views.py file for django-tinymce
