for those, who will try to run MultipleFileUpload with Nette/Database in Nette 2.3, this worked for me:

// Setup MultipleFileUpload in bootstrap.php

$db = $container->isCreated('database.default.context') ? $container->getService('database.default.context') : $container->createService('database.default.context');

MultipleFileUpload\MultipleFileUpload::register();

MultipleFileUpload\MultipleFileUpload::getUIRegistrator()
->clear()
->register('MultipleFileUpload\UI\Uploadify');

MultipleFileUpload\MultipleFileUpload::setQueuesModel(new MultipleFileUpload\Model\NetteDatabase\Queues($db));
