A while ago I started to play around with bokeh with the idea to create a data analysis web app. I implemented a couple of custom widgets in coffee script that worked in Bokeh 0.12.3. Now that I have updated Bokeh to 0.12.5 I get the following error message in the web browser:
Uncaught TypeError: Cannot read property ‘prototype’ of undefined

I attach a zipped version of an application that displays this issue.
