title: PrimeNg <component> is not a known element error (@angular-2.0.0 & primeng-1.0.0-beta.16)
body: <p>I started with Angular 2 RC5 and PrimeNG 1.0.0-beta.13 beta. I'm loading PrimeNg components as xModules and has no problems displaying Data Table, Input, SelectItem, Buttons, modals. However, I'm getting this error when I try to use TabView or Accordion.</p>
  
  <p>Unhandled Promise rejection: Template parse errors:
  'p-accordionTab' is not a known element:</p>
  
  <p>I imported the TabViewModule in the @NgModule. Currently, I updated my app to use Angular 2.0.0 (final) and PrimeNg beta.16 (latest) but still having the errors. I'm using webpack to chunk polyfills, vendor and app codes and I'm seeing accordion and tabview modules in the webpack-generated js files.</p>
  
  <p>I'm not sure what I'm missing. Let me know if you need more info.</p>
  
  <p>Thanks in advance!</p>
