It isn't possible because the child needs to be injected into two different parents. See the other duplicate interceptors test. Well, it is possible, but you have to do a horrible case statement (knowing all possible parents) like: http://anonsvn.jboss.org/repos/jbossas/projects/microcontainer/trunk/kern... This might be ok when you are dealing with a single model, but when you are trying to generate the model from annotations on a class it becomes very messy, if possible at all?
