title: Angular2 router - Navigate to the current page with different parameters
body: <p>I am trying to route to the current page with different param with no avail.
  I have a combo box that triggers:</p>
  
  <pre><code>this.router.navigate(['page', selectedId]);
  </code></pre>
  
  <p>the Url is changing but that's about it.</p>
  
  <p>How do I route to the same page with different param?</p>
