title: How to send var to view from event listener in symfony2?
body: <p>I am trying to send var to view from event listener in symfony2 but I am stacked. </p>
  
  <p>1) Is this possible?</p>
  
  <p>2) What kernel event to use (kernel.view or kernel.request)?</p>
  
  <p>3) Finally how to send some var to view?</p>
  
  <p>My best guess is that I have to extend return from controller and then to let controller do his job.</p>
  
  <p>I need to send some array of objects (entities).</p>
