It is fine for the controller to know the identity of the formats involved. But understanding them is probably overkill. A well designed system will often have situations where the view and model use the same format, meaning that there is no need for any adapter. _______________________________________________ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders
