title: JSF format an h:inputText while typing
body: <p>I'm constructing a page with pure JSF.</p>
  
  <p>On that page I've some field for dates... but I don't need a date picker. So I used an <code>&lt;h:inputText&gt;</code></p>
  
  <p>This is working when I type a valid date like 01/01/1970. But I need to type the "/".</p>
  
  <p>I want to put some mask on this input. How can I do that?</p>
