Sortable is not defined

[ghost]

I'm trying to recreate the Shiny app you demonstrated in your blog and have been able to successfully do so on a local Windows machine. However, when trying to run the exact same code on a Linux server, I get an error in the console:

ReferenceError: Sortable is not defined

Any thoughts on what might be going wrong? Thanks in advance!

very strange; my initial thought is case-sensitivity in the file name. Can you take a screenshot of the Sources window of your browser (Firefox or chrome) developer tools? I'll try to update to the newest sortable and use all lower-case and push to Github by the end of the weekend to see if that miraculously fixes the problem. Sorry for the trouble.

No need to apologize at all. Below are the screenshots you requested.

If these are not what you're looking for, or if you need more information, just let me know. Thanks again!

EDIT

It might be worth pointing out that these screenshots are from the Sources window for the app I'm actually building, not the example app from your blog, which might explain the abundance of sources included. Sorry for any confusion that might cause.

Would you mind trying reinstalling from Github? I changed everything to lowercase. Thanks.

[ghost]

That worked perfectly. Thank you for the quick turn around time!

Glad it worked. Please note, this was an early widget, so should be considered extra-alpha. I grimmaced quite a few times as I looked through the code.
