Re: MVC - not!

What you say makes sense, until you look at the actual pattern used that is called MVC. It was not until I tried stopping fitting what people were doing into what they said they were doing that I began to understand the pattern actually used, David. So, I have to respectfully disagree. I think the opposite in fact is true. I don't see anything like in the actual pattern, but just in the desired outcome. A pattern is not defined by its problem (the hoped for outcome) but by the solution. The MVC problem is the same in both cases, but the MVC solution is not what we use. Some, like Barracuda, come closer to the MVC.

Web MVC doesn't match conventional MVC from desktop GUI apps but I still consider them the same pattern. You have the same separation of concerns but with a slightly different message system between the components. IMO, calling it something other than MVC consuses the issue and is not helpful for a person trying to learn the pattern.

I know, David, and I admire your work.  But, look at the design pattern.
Ted Husted is right, I think, that it is not what we normally talk about.

I don't see an "E" (for events) in "MVC".

Wouldn't it be better if we stopped talking about MVC patterns when they really are not MVC patterns? The patterns usually called "MVC" are not because they have no event structure. We use, as a rule, a pattern that really is just based on minimal coupling, i.e., coupling only to contiguous operations. Isn't that right? The Model 2 maybe should be called the CD pattern, for "Contiguous Dependencies"?
