Cor,
I've found it the other way - trying to find complex examples of MVC are
hard - there are heaps of overly simple ones that don't really tell me a
lot about wiring complicated applications together.
Also, I recommend you take any advice/examples objectively. There are
many ways to skin an MVC cat.
Some frameworks are tightly coupled, some are loosely coupled, some use
dependency injection, some don't.
Some peoples examples have the logic in the controller, some in the
model. Some people use the controller to load data and the model to
store it. Some people extend the metaphor to MVCS ("S" for service -
using service classes to load external data).
There are so many different takes on it.
Here's a really basic tutorial fwiw. Again, I'm not sure I agree with
all of the methods involved, but like anything you can watch and learn
from it and apply the bits that make sense to you.

Personally, the more I look into Robotlegs the more I like it.
Especially now people are starting to consider AS3Signals as the event
method. This writeup says it all for me:
http://alecmce.com/library/robotlegspong1 There's even source code to
check the whole thing out.

Cor, if I can find some time, I'll try and send you a simple MVC
example. We'll see how tonight goes with my 2 year old.

My version is ActionScript 3 Design Patterns by William Sanders &
Chandima
Cumaranatunge.
The MVC there is describe as a combination of several other patterns.
The books is good, but I have to start at one level below that.
Is there somewhere a shareable example of the MVC pattern??

Cor,
I am only familiar with a part of it but the book ActionScript 3 Design
Patterns by Joey Lott and Danny Patterson from Adobe Press has a nice
example using an analogue and digital clock but only one set of data.
You can imagine a wrist watch view asking to get informed when the time
changes.
