[TYPO3-mvc] How to send Tx_Extbase_Persistence_ObjectStorage to a Controller action?

[Simon Schaufelberger (Schaufi)]

I was digging a bit deeper into the source code of extbase and found 
out: it is NOT possible at the moment. ;(

try it yourself in the blog_example:

create an action edit2 in BlogController (add it to ext_localconf.php):

/**
  * test function for editing multiple blogs
  * @param 
Tx_Extbase_Persistence_ObjectStorage<Tx_BlogExample_Domain_Model_Blog> $blog
  * @dontvalidate $blog
  */
public function edit2Action(Tx_Extbase_Persistence_ObjectStorage $blog){
	print_r($blog);
	die('in edit2 Action!');
}

and then call your page like this:

?tx_blogexample_pi1[action]=edit2&tx_blogexample_pi1[controller]=Blog&tx_blogexample_pi1[blog][]=5&tx_blogexample_pi1[blog][]=6

or

?tx_blogexample_pi1[action]=edit2&tx_blogexample_pi1[controller]=Blog&tx_blogexample_pi1[blog][][__identity]=5&tx_blogexample_pi1[blog][][__identity]=6

and what you should get is:

#1231178878: Given property name is not of type string.

It only works if you remove Tx_Extbase_Persistence_ObjectStorage from 
the function but then you just get an array and need to map the blogs to 
a collection by yourself.

Feature request???
