No, that's exactly what I'm trying to explain.
Component deployers should only consume attachments,
not create/generate them.

  |   | 			// only to component deployers

  |   |

  |   | 
  |   |    }

The moment you're hacking with getParent::addAtachment you know 
there is something wrong with how you're doing it.
I know we have something like that in our JPA deployers. :-(
