title: MVC3 - Model set to null but still entering IF statement
body: <p>I have a Model (BusinessPlaceDetailsViewModel) which has another Model (Hub) inside it.</p>
  
  <p>However if I set my Hub to null it still enters my IF condition, see here: </p>

  <p>I have tried loads of different combinations like putting each IF statement inside its own braces.</p>
  
  <p>Why is it entering the If block?</p>
