Clicking "Confirm" throw error: invalid parameters

Encounter error when clicking "Confirm". Looks like related to the latest changes on the stroke order color feature. Unfortunately i couldnt trace what's wrong from my local.

Strange..clearing the browser cache solved the problem. So i supposed the old javascript was cached in my Chrome browser...that's annoying..

The issue is with people having the old JavaScript file in their browsers. I have to find a way to prohibit this from happening.
