title: Adobe Flex Inactive Component
body: <p>I have a question about Flex. </p>
  
  <p>I want to add a check box so that when user clicks it, some fields in the form (<code>NumericStepper</code>, <code>TextInput</code> and <code>CustomDataField</code>) will be deactivated. My check box id is <code>'check'</code> and it has a click method. </p>
  
  <p>When user click the checkbox the fields will be inactivated. Then if user uncheck the checkbox, the fields above will become active again.</p>
  
  <p>How can I do so?</p>
