Help with SetFocus

I'm trying to implement a strategy where if a user does not enter a valid email format to my V2 textinput component the focus returns to that textinput field and forces the user to re-enter or accept the entry 'NONE'.

I've been able to get everything to work except the setFocus. Specifically, since this statement correctly sets the text value of the textinput:
 >myLogin.textInput_mc.email.text = "NONE";

it sure seems like this line should move focus to that same field.
 >myLogin.textInput_mc.focusManager.setFocus(myLogin.textInput_mc.email);

I don't get an error or anything...focus simply continues to the next textinput field instead of returning to the email textinput field.

emailListener.handleEvent = function(eventObj) {  if (eventObj.type == "focusIn")  {
  //formatting stuff
  myLogin.instructions_txt.text = "Enter email or 'NONE'.";  } else if (eventObj.type == "focusOut"){
  //formatting stuff
  if (!utils.ValidEmail(myLogin.textInput_mc.email.text) ||
       myLogin.textInput_mc.email.text<>"NONE")
  {
   myLogin.instructions_txt.text = "Want 'NONE'?";
   myLogin.textInput_mc.email.text = "NONE";
   myLogin.textInput_mc.focusManager.setFocus(myLogin.textInput_mc.email);
  }
 }
}
