I can answer the ModelLocator one.
ModelLocator is basically a class that holds all of your data. It acts like
a Singleton, and "Singleton is the new _global!"
So, where you are used to putting data on _global:
_global.my_array = [];
You instead put it on ModelLocator:
ModelLocator.my_array = [];
Secondly, since it's a static class instance, you can use it in any class
file:
import ModelLocator;
<mx:TextArea text="{ModelLocator.myText}" />
The key point, however, is that Flex supports binding better than Flash
does, and it's easy. If you notice in the above line, I use "{}" brackets
around the variable. This is shorthand binding. The TextArea will show the
value of ModelLocator.myText, and anytime ModelLocator.myText's value
changes, the TextArea will update.
Since you can pretty much bind to any datatype, this is a wondeful way to
bind your View's to data vs. calling set methods, etc.

Subject: [flexcoders] Newbie Question.
Hi,
Flash Developer since about 3 years now, i'm currently working on a
classical Flex Store prototype, integrating it with ATG Dynamo 6.4.
We are trying to use the Cairngorm Framework, and i've read the
"ActionScript Design Patterns for Rich Internet application
development" PDF iteration::two provides on its website and the 0.99
release notes.
The fact is that i have some problems understanding the new concept
that appeared in Cairngorm 0.99 : ModelLocator and ViewLocator (its
not really explained in the previous documents :/) and how to use them.
Is there any documentation, crystal-clear explainations and cool uml
schemas i can work on so i can become a killer-flex-developper in 2
days?:)
more seriously, i'm really in need of some explainations on this (and
sorry if the question has been posed hundred of times).
Thanks to anyone who can give me a clue,
Antoine
