title: Symfony 1.4, form based on model, I dont need some widgets
body: <p>In Symfony 1.4 Im using a form based on model. But there are some widgets/fields I must need to validate. I couldnt find <code>removeWidget()</code> or something like that, how to remove some fields not to be checked/validated?</p>
  
  <p>EDIT: baseForm</p>
  
  <pre><code>$this-&gt;setWidgets(array(
    'f1'          =&gt; new sfWidgetFormInputHidden(),
    'f2'  =&gt; new sfWidgetFormInputText(),
    'f3'    =&gt; sfWidgetFormInputText()
  ));
  
  $this-&gt;setValidators(array(
    'f1'          =&gt; new sfValidatorChoice(array('choices' =&gt; array($this-&gt;getObject()-&gt;get('ID')), 'empty_value' =&gt; $this-&gt;getObject()-&gt;get('ID'), 'required' =&gt; false)),
    'f2'  =&gt; new sfValidatorInteger(),
    'f3'    =&gt; new sfValidatorInteger()
  ));
  $this-&gt;widgetSchema-&gt;setNameFormat('task[%s]');
  $this-&gt;errorSchema = new sfValidatorErrorSchema($this-&gt;validatorSchema);
  $this-&gt;setupInheritance();
  parent::setup();
  </code></pre>
  
  <p>and now somehow I must edit the <code>configure()</code> method so that validator wont check 'f1' field.</p>
