title: Flex form inside Pop up window - Tab (order) between forms not working
body: <p>when user clicks on Add button, then a pop up button will be opened with certain form elements (like textinput, date field, text area).. When i used 'TAB' inside this form,it is not working. I found in couple of Questions / forums that we need to create an instance of FocusManager and then  bring/activate focus for the pop up. But still i didn't see the tab working inside the form. In order to tab order working inside a pop up, what steps we need to follow.</p>
  
  <p>I tried using focusmanager and property like tabfocusenabled, tabenabled and also added taborder inside each form element. But no luck.</p>
  
  <p>Iam using Flash Builder 4.5 and using spark components for development.</p>
  
  <p>Is there any workaround for this problem? </p>
  
  <p>Thanks in Advance,</p>
  
  <p>Regards</p>
