Here's a fragment of documentation from the "Cocoa Bindings Programming Topics" guide:
"In order for a controller to create new content objects automatically or in response to the target-action methods, it must know the appropriate class to use." My question is: what is a real example of a case when the controller needs to create new content objects? As far as I see, it can only happen when a view sends addObject to the controller, but in that case the object is already created and the controller simply adds it to the collection. Have I missed something? Also, if the controller does need to know the class/entity of the content object, what about polymorphic objects? I.e. I have one abstract entity "Shape" which is not directly instantiatable, and a few concrete subclasses. What entity should I specify? _______________________________________________ Cocoa-dev mailing list ([email protected]) Please do not post admin requests or moderator comments to the list.
