I want to support the New/Open/Save/SaveAs cycle for Reports [...] But how do I implement SaveAs ? By the time I know the end user wants to make a new object, the old one has already been messed up.


Thinking about it, one solution out of this problem is to drop the SaveAs command (posterior to changes) and replace it with a Duplicate command (prior changes). Like in Mac OS X Lion Laugh | :laugh:

Then what would Save mean ? Worse, what would it mean if a user changes the data, then never executes Save ?

It seems to me that MVVM may end up curbing the way we design UIs. Another example, it discourages modal dialogs, or at least it makes them difficult to implement.

I wonder if it's legitimate for a code pattern to have such impact on the end-user experience. Isn't it the tail that wags the dog ?
edit: grammar
