Uncaught TypeError: Object #<Object> has no method 'register

on this page dhtmlx.com/docs/products/dhtmlxG … extra.html

we have a demo for “clist”

but I can’t find these files in my dhmlxGrid package:

and when I use this function:
mygrid.registerCList(2, [“Role001”, “Role002”, “Role003”]);

I got error:
Uncaught TypeError: Object # has no method 'register.

Any answer, will be helpful

the full error is:

Uncaught TypeError: Object # has no method ‘registerCList’

unfortunately the issue cannot be reproduced locally.
Please, provide with a detailed sample of your code or a demo link, where the issue can be reconstructed.

@sematik yes, you are right. thx
