Strange error

Hi all!
What does mean following error message in the browser’s console?

Uncaught TypeError: webix.p[t].call is not a function

At the same time all main functionality seems work -my page is shown correct and the data is loaded from a server and shown in a listview.

My HTML file is opened as simple file in a Chrome from local filesystem.

Chrome: 48.0.2564.116 m

Webix: 3.2.0

An answer is there:
