Hi,
I had the same problem with the joomla login page appearing after a session timeout (so the user sees 2 logins - Joomla and Community Builder), even though I'm using the Community Builder login and the joomla login is disabled. So here is a brute force solution that works for me (running Community Builder 1.2RC3 and Joomla 1.5.7 - legacy mode):
1) Find the following folder in your joomla root:
/components/com_user/views/login/tmpl
2) In that folder, rename the default_login.php file to something like original_default_login.php - in case you want to revert back to it later.
3) Then put in a new default_login.php file with a file that has these 2 lines:
<?php defined('_JEXEC') or die('Restricted access'); ?>
<?php mosRedirect( 'index.php' )?>
Now, when the sessions times-out it will redirect back to your home page login, without the joomla login showing up as well.
I'm sure that there must be a better solution than this, but it works.
