title: show details row's datatable
body: <p>I've got a datatable in a .xhtml page, that shows products of a database.
  Let's say that I can only see Name and Code for every row, how can I show more detail of the product in the same page?</p>
  
  <p>Moreover, my product bean is in ViewScope, so i'm not able to show details in another .xhtml page (I've tried many times, but if in case you guys have a solution for this, that's good).</p>
  
  <p>PS: I don't know anything about Javascript yet, so i'd prefer mostly solutions based on jsf and java :)</p>
