Couldn't deploy webix.js to Tomcat

Webix JS
1

I can run the pivot table sample codes in Apache PHP. But when I put it in Tomcat, it gives an error:
webix_debug.js:4413Uncaught TypeError: e[i] is not a function
I have no clue what’s the reason or how to fix it. Please advise.

Do you have any errors in your Tomcat error logs? (IE files not loading, bad path, ect)

Please be sure that you have included both files webix.js and pivot.js

The above error occurs when code attempt to create a non-existing view ( which means that you have typo in a view name, or pivot.js is not included on the page.
