What is wrong with array filter?

Question

1C-Bitrix

I make the filter like this:

$GLOBALS['arrFilterTomain'] = Array("ACTIVE" => "Y",
 "PROPERTY" => array('CITYS' => array('VALUE_XML_ID' => '2012'))); 
//ничего не выводит

-------------------------------------------------- -----------------
An example of working filtering from the same feed

//$GLOBALS['arrFilterTomain'] =Array("ACTIVE" => "Y", 
"PROPERTY" => array('TOMAIN' => array('VALUE' => 'Y')));

            }
          }
          ...

          string(1) "Y"

          ["~DEFAULT_VALUE"]=>
          string(1) "Y"
        }
