RangeSlider error?

When I’m trying to use RangeSlider, I get error “e[i] is not a constructor” at webix.js:153:7 (Webix GPL). I’m creating RangeSlider widget like this:
var rng = { view:“rangeslider”, label:“Range Slider”, value:“0,50” };

Is RangeSlider available in Pro version only?

Yes, it’s a part of the pro version, as mentioned in the RangeSlider docs.

Yup, I missed it, because it doesn’t have the PRO badge in the left side menu in th docs. Sorry for that.
