title: AngularJS ng-if problems with 'f' and 'F'
body: <p>Can anybody explain to me why Angularjs <code>ngIf</code> directive reads 'f' and 'F' like <code>false</code>?</p>
  
  <p>Simple example which does not work:</p>
  
  <pre><code>  &lt;input type="text" ng-model="test" /&gt;
    &lt;div ng-if="test"&gt;{{test}}&lt;div&gt;
  </code></pre>
  
  <p>If you put 'f' or 'F' nothing shows in div, any other letter or sine works ok.</p>
