[FLOW3-general] Exception by Doctrine

[Georg Grossberger]

Hi list

I'm currently working on a (rather big) domain model. The problem is, 
FLOw3 seems to ignore the Collection class / interface when building the 
database schema for :create or :migrate operations.

Example
A class like this:

<?php
namespace My\Package\Domain\Model;

use TYPO3\FLOW3\Annotations as FLOW3;
use Doctrine\ORM\Mapping as ORM;

/**
  *
  * @FLOW3\Scope("prototype")
  * @FLOW3\Entity
  */
class Inventory {

	/**
	 * Items
	 *
	 * @var 
\Doctrine\Common\Collections\Collection<\My\Package\Domain\Model\Item>
	 * @FLOW3\Lazy
	 * @ORM\ManyToMany
	 */
	protected $items;

	/**
	 * Constructor
	 *
	 */
	public function __construct() {
		$this->items = new \Doctrine\Common\Collections\ArrayCollection();
	}
}
?>

running "./flow3 doctrine:update" ends like this:

More Information
   Exception code      #1295973082
   File 
...\TYPO3_FLOW3_Persistence_Doctrine_Mapping_Driver_Flow3AnnotationDriver_Original.php 
line 80


A quick look at the code revealed, that Doctrine asks the FLOW3 driver 
for the meta data for \Doctrine\Common\Collections\Collection or 
\Doctrine\Common\Collections\ArrayCollection. FLOW3 does not load those 
information and throws an exception instead.

What am I missing?

Greetings,
