[Flow] Get Argument like GET

[Patric Eckhart]

Hey,

I have a link with new?object%5B__identity%5D=d6622342-fc86-af21-82a1-252723028f29

and in my Controller I have added ...

$object = $this->request->getArgument('object');
$this->view->assign('object', $object);

.. in the newAction.

I would show the object identifier with <f:format.identifier>{object}</f:format.identifier>

How can I get this?
