title: PrimeFaces OneRadio + "spacebar" key
body: <p>I have added radio buttons to various forms and even though I can focus on the radio buttons with "tab" I can not choose them pressing "spacebar". 
  The arrow keys work so I can circle between the two radio buttons I have, but I need the "spacebar" functionality. With normal  this works ok, not with  though.</p>
  
  <p>Is this some kind of bug or is there a workaround?</p>
