title: Vaadin one to many and Grid binding.Property not found
body: <p>There is the Customer entity which has a one to many relationship to entity Address,so there is a <code>List&lt;Address&gt;</code> getAddress in Customer.Address has an Email field.</p>
  <p>So for instance to get an email from the first customer you do customer.getAddress.get(0).getEmail</p>
  <p>When I bind to a Customer.class grid,setColumns(&quot;customerid&quot;,&quot;address.email&quot;) it throws an exception Property not found.</p>
  <p>If I do addColumn(customer-&gt;customer.getAddress.get(0).get email).setHeader(email) it does display the email.</p>
  <p>But that's for the first customer.How to do the same for all customers?</p>
