Doesn't work "keep" option

$client = new Ext_Riak();
$bucket = $client->bucket("test");

$bucket->newObject("foo1", 111)->store();
$bucket->newObject("foo2", 222)->store();
$bucket->newObject("foo3", 333)->store();
$bucket->newObject("foo4", 444)->store();

$foo1 = $bucket->get('foo1');
$foo2 = $bucket->get('foo2');
$foo3 = $bucket->get('foo3');
$foo4 = $bucket->get('foo4');

$foo1->addLink($foo2)->store();
$foo2->addLink($foo3)->store();
$foo2->addLink($foo4)->store();

$object = $bucket->get('foo1')
->link('', '', true)
->link('', '', true)
->map("Riak.mapValues")
->run();

print_r($object);

OUTPUT:

(
[0] => Array
(
[0] => Array
(
[0] => test
[1] => foo2
[2] => test
)

    )

[1] => Array
    (
        [0] => Array
            (
                [0] => test
                [1] => foo3
                [2] => test
            )

        [1] => Array
            (
                [0] => test
                [1] => foo4
                [2] => test
            )

    )

)

I can't get a values of objects.

mapValues may not work on phases such as link which return links rather than values.

Suggest mapping values separately.
