title: cakephp form input default value
body: <p>I'm trying to create a simple form to edit users, but I can't view the default value for my input type why?
  Here is the code of my view</p>
  
  <pre><code>&lt;?php
  echo $this-&gt;Form-&gt;create('User');
  foreach ($users as $user){
      echo $this-&gt;Form-&gt;input('username', array(
          'type' =&gt; 'text',
      'default' =&gt; 'default value',
      ));
  }
  echo $this-&gt;Form-&gt;end('Edit');
  ?&gt;
  </code></pre>
  
  <p>In the page html the input type is empty and in source:</p>
  
  <pre><code>&lt;input id="UserUsername" type="text" value="default value" name="data[User][username]"&gt;
  </code></pre>
  
  <p>The value is in the html but I can't see into my page!</p>
