[Flow] Error: The property "***" on the subject does not exist. (1302855001)

[Kevin Sam]

I have a model (Acl) in which i have a protected property named as aclFiles (which is a doctrine collection) which is a OneToMany relation to another model(file (which has a manyToOne relation pointing to the property *aclFiles*)) . I do have a getter for that property but for some unknown reasons flow is dumping me a  property doesnt exist..

Sample Code (relevent parts)
// Acl.php
==============================

	/**
	 * @var \Doctrine\Common\Collections\Collection<\Doc\FileManager\Domain\Model\File>
	 * @ORM\OneToMany(targetEntity="\Dev\FileManager\Domain\Model\File",mappedBy="acl")
	 * @ORM\JoinColumns({@ORM\JoinColumn(name="file_id",referencedColumnName="id")})
	 */
	protected $aclFiles;

	public function __construct()
	{
		$this->sharedUsers=new \Doctrine\Common\Collections\ArrayCollection();
		$this->sharedGroups=new \Doctrine\Common\Collections\ArrayCollection();
		$this->aclFiles=new \Doctrine\Common\Collections\ArrayCollection();
	}
	public function addAclFiles(\Dev\FileManager\Domain\Model\File $file)
	{
		$this->aclFiles->add($file);
	}

	public function removeAclFiles(\Dev\FileManager\Domain\Model\File $file)
	{
		$this->aclFiles->removeElement($file);
	}

	public function getAclFiles()
	{

		return $this->aclFiles;
	}

And on File.php Entity i have,
=========================== 

	/**
	 * @var \Dev\FileManager\Domain\Model\Acl
	 * @ORM\ManyToOne(targetEntity="\Dev\FileManager\Domain\Model\Acl",inversedBy="aclFiles")
	 * @ORM\JoinColumns({@ORM\JoinColumn(name="acl_id",referencedColumnName="id")})	
	 */
	protected $acl;

And, i was able to get a workey version on a core doctrine build. So just wanted to check whether this  is an *issue* related to Flow.
