title: Symfony forms: display a checkbox (with initial state of unchecked)
body: <p>I am using Symfony 1.3.x for a project.</p>
  
  <p>In the configure() method of one of my forms, I have the following code:</p>
  
  <pre><code>'terms' =&gt; new sfWidgetFormInputCheckbox(array('value_attribute_value'=&gt;'terms', 'default' =&gt; false )),
  </code></pre>
  
  <p>The idea is to present the user with a checkbox (default unchecked), which the user will have to check before the form validates. </p>
  
  <p>The problem is that when I display the form, the checkbox is ALWAYS already checked (i.e. selected) - which defeats the purpose of enforcing user confirmation with a checkbox.</p>
  
  <p>Does anyone know how to resolve this?</p>
