Help needed "tabEnabling" not working in simple login page

Hello Friends,

I need a small help in Flex. I am doing a simple login page application in FlashBuilder 4.0 & i have kept 2 input boxes like Login,Password and a submit buttion. On clicking the button i am calling a method, so far everything is working fine… But some how tabenabling is not working. suppose if you are in login inputbox and i press “tab key” it has to go to password input box… but its not working. can any one help me on this, why it is not working. i have tried all the attempts using tabEnabled = “true”. but stil i am failing to do this.

i am attaching the code as a text file along with this. pls go thru it.

your help would be appreciated.
