php-dbo backend issue with tables/views not found in information_schema.statistics when building $keys[] index

[GoogleCodeExporter]

What steps will reproduce the problem?
1. click save/load
2. select backend php-pdo 
3. click import from DB
4. Enter a database that has tables that aren't listed in the 
information_schema.statistics table.  Or a database that has VIEWS.
5. Alternative Step: 
Navigate to 
http://localhost/wwwsqldesigner-2.7/backend/php-pdo/index.php?action=import&data
base=[database]

What is the expected output? What do you see instead?
Steps 1 -4:
Expected output is the database er diagram.

Instead an alert is presented:
XML error: NULL Output

Step 5:
Expected output is XML data representing the database er diagram.

Instead a php alert is issued for an undefined index on line 174 of 
LayerMYSQL.php

What version of the product are you using? On what operating system?
Version: 2.7
OS: Windows 7
WAMP stack

Please provide any additional information below.
Problem:
public static function Keys($table)
{
...
line 174: return self::$keys[$table['name']];
...
}

Doesn't take into account that the table name might not exist in the 
information_schema.statistics table and therefore not be an entry in the 
$keys[] index.

Fix:
Mimicked the public static function Relations() return if clause:
public static function Keys($table)
{
...
if(isset(self::$keys[$table['name']]))
return self::$keys[$table['name']];
return array();
...
}

Thanks!
Jeremy
