Ah, I read it as "that's not always the case: consider the following example".

Sure. I should have been more explicit about that. I got the
impression from the OP that he was talking about mediating controllers
(in which case I would argue that my rule of thumb is well-aligned
with the principles of MVC) rather than co-ordinating controllers.

I think it's plain what the OP was trying to do: tie the detail in a
master-detail interface to an object newly added to the collection.
However, as he seems to be using some sort of custom navigation
controller, I can't be sure ;)
