title: Open particular object from button or menu
body: <p>How can one open a particular object when pressing on a menu item or a button? It's useful if you want to have a sort a configuration-like object (only one object is needed to hold data e.g. username and password).</p>
  
  <p>I've tried playing with <code>view_init</code> method and <code>active_id</code> context key, but with no luck. Can somebody point me to the right direction?</p>
