Hello,

I am trying to create a custom MVVM widget. I noticed that when my widget is bound and the "visible" binding is declared -- this error logs in the console:

typeError: cannot read property '0' of undefined. 

 

I have created a dojo from an example provided in your tutorial on how to build a custom widget and am able to reproduce:

https://dojo.telerik.com/ayaQEsaV

 

Please advise.

Hi,

The widgets rely on a "wrapper" property being available. In general it's the same as the element property, so you can do the following:
