title: Failing to get hook_form_alter to work
body: <p>I'm trying to investigate how to add functionality to a webforms form (want to add a lookup button to populate the form). The issue is that I don't seem to be be able to get hook_form_alter to work as I would expect.</p>
  
  <pre><code>function myModule_form_alter(&amp;$form, &amp;$form_state, $form_id) {
       $form['test'] = array('#markup' =&gt; 'testint 123');
  }
  </code></pre>
  
  <p>I know that this would effect ALL forms as is. I'm keeping it <em>simple</em> while I test that it's working correctly. </p>
  
  <p>I have a webforms form and would expect the markup to appear on the page, but it's not.</p>
