title: problems with password field in EXT 3.0
body: <p>I am having problems with a password field because it doesn't shows properly the emptytext that I pass through the config object, here is my code:</p>
  
  <pre><code>                            {xtype: 'textfield',    
      inputType: 'password',
      emptyText: '//Password',
      width: 200}
  </code></pre>
  
  <p>the problem is that the EmptyText looks like a password too and users can't read it. Please helpme with this, thanks in advance.</p>
