Christian, I think you're hitting https://issues.apache.org/jira/browse/TAP5-2156
There is very little code to the Radio component. I think RadioGroup is where the support for client-side validation is missing. If you are so inclined, it should be easy to copy RadioGroup.tml into your project, and then you could add the missing functionality as an experiment. Let us all know what you find out.

(I want to add a required validation rule to a radio group btw) Or am I missing something? Cheers Christian
