Bug report

When a Kendo UI RadioButton is bound to a null or undefined value, an uncaught TypeError exception fires.

Reproduction of the problem

Please take a look at the following Progress Kendo UI Dojo which demonstrates the error firing.

Expected/desired behavior

When a null or undefined value is set, the RadioButton should be set to false.

Environment

• Kendo UI version: 2022.2.802
• jQuery version: All Supported Versions
• Browser: all

The commonly understood semantics for radio buttons is that the selected radio button is filled on the inside (e.g. with a foreground color). The new styling does not fill the inside, and as such is a bit more confusing. I had to do a double-take at first, even though I had developed the screen I was looking at. It's important for a design to use standard and shared understandings that immediately communicate with the user.

Change the style back to a filled in circle, and for the Bootstrap 3 theme in particular please change it back to match Bootstrap 3.
