[news.eclipse.modeling.mdt] Re: Creating objects with multi-valued child

[Kenn Hussey <Kenn.Hussey@xxxxxxxxx>]

Doug,

Yes, modifying the factory to do additional initialization for newly 
created objects would make sense. An alternative would be to attach a 
listener which detects creation/addition of a new car and responds by 
creating/adding the necessary tires.
