[Arp] ModelLocator - Events

[nyls]

MMM I got another version of Christophe's arpx extensions, where the model
dispatches change events when it's value is set. I can send you my arpx
extensions offlist if you want ? 

Further more different views can listen to one model an act differently on
model changes.. Like a view displaying the list of books , and a view
displaying a number of the total books .. but off course there can also be
only one model for one view . Depends on the app I think.

I'm not sure to have the last version of Christophe's ModelLocator : the 
one I have doesn't have event dispatcher methods... I took it from the 
list's archive here :
http://ariaware.com/pipermail/arp_ariaware.com/2006-January/000873.html

Also I'm not used to use several Models, but from what I understand, a 
Model here is a set of data most of the time related with a view? For 
example a customerList Model's data will be an array of objects with 
customerName, customerEmail, customerOrderAmount and will be used to 
feed a DataGrid in a CustomerList form. Or a customerInfo will feed a 
CustomerInfo view and will feature firstname, lastname, address...

Is this the way Models are to store data?
