Hello,

I'm not sure if this is a regression or if this is on purpose due to the changes made to fix CVE-2012-6432, but we can't seem to be able to pass objects to subrequests anymore, only scalars, after having updated to the latest sf 2.2.

For example, what used to be:

{% render "SomeBundle:Foo:Bar" with {'someObject': someObject} %}

Should now become:

{{ render(controller("SomeBundle:Foo:Bar", {'someObject': someObject}) }}

However if someObject is an instance of SomeObject, this will throw an exception saying that the action "...requires that you provide a value for the "$someObject" argument...". The action signature being public function widgetAction($someObject). When adding typehinting (widgetAction(SomeObject $someObject)), an "Unable to guess how to get a Doctrine instance from the request information." error is thrown (adding a ParamConverter doesn't help)

The ability to pass objects was quite handy, especially to avoid reloading entities based on their ids in re-usable widgets/partials. Has this feature been removed deliberately? (or maybe am I doing something wrong?)
