title: Can't set default value
body: <p>Using  drupal 7 I try to render only one field. Code:</p>
  
  <pre><code>$form = array();
  $form['pager2'] = array(
      '#type' =&gt; 'select',
      '#title' =&gt; t('page'),
      '#options' =&gt; array('1'=&gt;'1', '2'=&gt;'2'), 
      '#default_value' =&gt; '2',
  );
  $page.=drupal_render($form);
  </code></pre>
  
  <p>Default value in any case is '1'. What i've done wrong?</p>
