I am trying to validate a required field using a radio button. Everything works as expected when selecting the radio button with the mouse. If I tab to the radio button and arrow to make my selection it triggers a validation error. Even though the arrowing over has made a selection by default. see pic below.

Select the ID textbox and enter the value 1.
Tab to the Radio button by pressing the tab key.
Arrow right or down to change the selection to no.
Radio button triggers the validation error. Even though the option No is selected.
