Hi Richard,
Thanks for bringing up MVCS.
I should have added it to the subject line as well.
Its good to hear a success case of the use of MVCS
I haven't seen read up enough on Joe Berkowitz's work to comment
enough but it looks good from a far.
The Singleton issue in Cairngorm is a pain that I've had to deal with.
I totally agree with the points brought up in the presentation.
I have not really seen the benefit yet of Dependency Injection and
using Prana, but thats probably because of ignorance as i didn't
really delve into it.
regards,
Bjorn

When I started Flex development in earnest a couple of months ago, I
looked at Cairngorm and had some of the same concerns raised in the
SilvaFUG presentation - mainly the Singleton issue, but also the type
casting necessary to get event data into commands, and the amount of
boiler-plate.
My current efforts are modelled on MVCS/ReviewTube, and I feel pretty
good about it. But I dispatch bubbling events from views, rather than
calling Controller methods there. At the top level, I invoke the
controller methods, and I like having a controller class with
type-safe methods, that invokes Operations. I've not missed implicit
invocation so far, but the application is admittedly not yet very
large. Given the convenience of anonymous function callbacks, the MVCS
Operations (which are NOT equivalent to Cairngorm Commands) seem to
work quite well. To address the mild objection (where's the shared
code?) raised in the SilvaFUG video, the tiny Operation base class is
about the only piece of MVCS/ReviewTube that I could imagine sharing.
After attending James Echmalian's talk at 360 Flex/Seattle
(http://ech.net/360flex2007/), I was anxious to see updated sample
code, because I'm sure Allurent has learned a lot since the MVCS
article was written, but I have been unable to reach James or Joe.
I'm a big proponent of Dependency Injection (having used Spring in
server-side Java work), and I like the way Joe achieves this in a
simple way with Components.as/mxml, though I'll be keeping an eye on
Prana.
I am now motivated to look at PureMVC when I get a chance.
