title: GWT RequestFactory - different views of 1 EntityProxy
body: <p>I have one DocumentEntityProxy with the following methods :</p>
  
  <pre><code>String getAttribute1();
  void setAttribute1(String s);
  String getAttribute2();
  void setAttribute2(String s);
  String getAttribute3();
  void setAttribute3(String s);
  </code></pre>
  
  <p>What I want to achieve is that if you are a standard user you can only use getAttribute1() and setAttribute1() if you are an admin user you can use all methods. In this example I have only three attributes  and 2 different kind of users but in a real project there are a lot more of course.</p>
  
  <p>What is the best way to achieve that ? </p>
  
  <p>Thanks in advance for your help.</p>
