[fw-db] Zend_Db_Table and update

Hi there,

what is wrong with this code?

$msg_table = new MessageCenter_Db_Table_MsgctrMessages();
$msg_table->update(
array(
'folder_id' => self::FOLDER_TRASH
),
array(
$msg_table->getAdapter()->quoteInto('owner = ?', $this->_account->name),
$msg_table->getAdapter()->quoteInto('folder_id = ?', $id)
)
);

I receive an exception:
> SQLSTATE[07001]: <<Unknown error>>: -99999 [IBM][CLI Driver] CLI0100E
> Wrong number of parameters. SQLSTATE=07001

That exception comes up normally if not all of the ? in a query are replaced.

If i trace the exception i get this output :

[file] => /usr/share/php/Zend/Db/Adapter/Pdo/Abstract.php
[line] => 220
[function] => query
[class] => Zend_Db_Adapter_Abstract
[type] => ->
[args] => Array
(
[0] => UPDATE MSGCTR_MESSAGES SET folder_id = ? WHERE (owner = 'Gawalione') AND (folder_id = '6')
[1] => Array
(
[0] => 3
)
)

So this looks ok.
What is my failure?
