title: Symfony3: is it possible to change the name of a form?
body: <p>With <strong>Symfony 2.7</strong>, you could customize a form's name in your EntityType class with the method <code>getName()</code><br>
  This is now deprecated. Is there another way to do that with <strong>Symfony 3.0</strong> ?<br>
  I have custom prototype entry_rows for collections that I would need to use in different forms.<br>
  Since the name of the rows is based on the form's name, I would need to change the later in order to use them with a different form.</p>
