Log In Undefined issue in Siebel Open UI

In some of our environment, we noticed that Login button is showing as Login Undefined.

Solution to this problem.
From support web

1. On "CC Login Page (Login Only)', locate the "LoginButton".
2. Remove the Caption String Override.
3. Open UI script need to have nothing but HTML code in the caption. Otherwise, it will returns "Undefined" condition.

This did not worked for me due to some reason. The alternate way I used is by editing LoginSWT.

<script language="javascript" src="23030/scripts/3rdParty/jquery.js?_scb="></script>

<script>

$(document).ready(function(){

            $(".loginButton a").text("Login");

     });

</script>​

started working perfectly ;-)
