Missing icon after update from Webix 6.4.4 to 7.0.0

I the my application I don’e see the icon after the update from Webix 6.4.4 to 7.0.0
Have you changed the css?

Thanks

I have understand the mistake, in the version 7 we can not use view: “button” with type “iconButton”

Deprecated content types and their new substitutes:

type:”imageButton” => type:”image”
type:”imageButtonTop” => type:”imageTop”
type:”iconButton” => type:”icon”
type:”iconButtonTop” => type:”iconTop”

Thanks
