problem with DBManagerFactory

[pam81]

Hi, I'm using sugar and when I login, I receive this warning:

Notice: Undefined index: listviews in D:\Apache\htdocs\sugar\include\database\DBManagerF actory.php on line 65

I can do all without problem but I don't know why I receive this notice.
I search in the code and in include/listview/listviewdata.php there is the function that call the function that makes the warning

function ListViewData() {
$this->limitName = 'list_max_entries_per_page';
$this->db = &DBManagerFactory::getInstance('listviews');
}


this is the function where the warning is happening. include/database/DbManagerFactory.php
public static function getInstance(
$instanceName = ''
)
{
global $sugar_config, $dbinstances;
static $count, $old_count;

if(isset($instanceName) && $instanceName != ''){
$config = $sugar_config['db'][$instanceName]; //here is the problem!!

}else{
$instanceName = 'db';



Any idea is welcome !!

Thanks

I can resolve the warning making a chance on config.php

'db' =>
array (
'mysql' =>
array (
'db_host_name' => 'localhost',
'db_host_instance' => 'SQLEXPRESS',
'db_user_name' => 'root',
'db_password' => 'xxxxxx',
'db_name' => 'xxxxx',
'db_type' => 'mysql',

),
'listviews'=>'', //I put this to stop the warning
),

It's ok? there is a problem with this? I would like to know why is this .

thanks
