Description

When using a self-referencing relationship, for example:

  /**
   * @ManyToOne(targetEntity="Collection")
   * @JoinColumn(name="parent_id", referencedColumnName="id")
   * 
   * @var Collection
   */
  protected $parent;

ActiveEntity::toArray() recurses through all parents and children.

This was all working fine until my database actually started getting some data... then XDebug stopped me with a "Maximum function nesting level of '100' reached, aborting!" error.

The PersistentCollection object does not have a state so cannot be locked in the same was as an ActiveEntity object can - maybe it needs a lockable state for this to work?
