Yeah, while I am using this method, I realized after I posted this that this
probably wasn't a good use for this technique.
I am using this technique of passing the parent to the child as a form of an
app manager. The parent being the app manager. And by passing a reference
of the parent to the participating child app, the child app can ask teh
parent for the right service. Like I have a VendorManager as a app manager
for a CRM system. VendorManager has methods such as getUserService and
getCatalogService and getTerritoryService. So if the territory app wants to
get details about a user from the user app, it asks its compositional parent
to return teh right service to it.
Does this seem a more valid reason to use this technique?
