title: How can I clone (or copy) a object to another one, but don't copy PK attribute?
body: <p>I'm trying to copy all object attibutes to another object, fox example:</p>
  
  <pre><code>Person p1 = new Person();
  p1.name = "John";
  p1.sex = 'M';
  Person p2 = new Person();
  p2 = Util.Clone(p1);
  </code></pre>
  
  <p>The problem is that Person entity has an identity PK 'codPerson' and I don't want to copy this PK. Is there a way to clone/copy an object, but don't copy its PK attribute??</p>
  
  <p>Thanks!!!</p>
