Error message using $set

[yunosh]

The following code snippet works fine with using ext/mongo directly:

            $res = $this->_db->findAndModify(
                array(
                    self::SID => $id,
                    self::LOCK => array('$exists' => $exist_check)
                ),
                array($data),
                array(self::DATA => true),
                array(
                    'update' => array('$set' => $data),
                    'upsert' => !$exists
                )
            );

but throws the following error when using mongo-php-adapter:

MongoResultException: exception: The dollar ($) prefixed field '$set' in '$set' is not valid for storage.

Fixing this in #122.

Out of curiosity: why are you passing both an update parameter and the update option? Normally you'd only specify one. This confused me for a moment, especially since what you're passing in the update parameter is different from what the update option would apply.

No idea, that was code contributed by someone else.
