If we are referencing a radio group (all radios have the same name) in a check dependency (using @QueryParameter [@RelativePath] or checkDependsOn), the validation behavior add a listener on the change event only for one of the radio, or we need to be notified on all of them to retrigger validation. This is happening in the registerValidator because the findNearBy call returns only the first radio.

I think there should be another check to grab all radio with the same name on the same for level if the returned value is a radio.
