Piping the Machine: PureMVC Multicore with Pipes and the Finite State Machine (FSM)
This is going to be a walkthrough of making use of PureMVC Multicore (AS3). To help in building a PureMVC Multicore application, we are going to make use of the StateMachine utility for initial setup and configuration as well as the Pipes utility for communication between cores.

So what’s up with PureMVC Commands anyway?
That is what Jesse Warden (JesterXL) asks the fine folks over at the PureMVC forums. Cliff gives a good rundown on the why/when/how of PureMVC Commands.
PureMVC’s relatively light use of commands, when compared to other widely used MVC frameworks, tends to make one think they are doing something wrong. This isn’t really the case. Commands are still viable actors in our applications, but many times the shortest route is the best route. PureMVC doesn’t force us to use them, but gives us access when we need to.
I generally use PureMVC Commands for actions that can be initiated from several places, as well as for application startup. I’ve also found them very useful for popups and AIR window management.

Introspective PureMVC Console
This project is intended to help Flex and AS3 application developers, that use the PureMVC framework for AS3 – simple or multicore version – by providing them deep insights on what happens at the framework level: Notifications, Commands, Mediators and Proxies.
PureMVC is a highly recognized MVC framework, that has also many portages in various languages, and that’s now quite widely in Flex applications, though not as much as Cairngorm.
What a fantastic tool. You can really dig deep into your application.
- Monitors the internal flow of PureMVC in real time
- Discover and inspect Mediators
- Inspect Views associated to Mediators
- Discover and inspect Proxies
- Find starting point in source code
- Integrated with KapInspect

Fabrication – Simplified PureMVC multicore modules (and more)
One of the many reasons I love PureMVC is the community of highly intelligent, skilled, object-oriented (oriented) programmers that are constantly using the framework to build new and interesting utilities. This is a by-product of the very nature of PureMVC. Cliff architected the core framework in such a way that is is truly simple, providing a base from which to build new useful structures.
Fabrication, a new utility developed by Darshan Sawardekar is a shining example of this fact. He has taken the PureMVC multi-core apperatus, combined it with Cliff’s Pipes utility, and created a wonderfully abstracted means for creating modular PureMVC applications. Not only does this simplify the connection of modules in your application and allow them to communicate seamlessly, but he provides a router/firewall metaphor for controlling the communication as well as undo/redo functionality.
Thanks Darshan, your efforts are appreciated. And as always, thanks Cliff for providing the base from which our community can build and contribute. Cheers.

Continuous scrolling image thumbnail component for Flex.
Here is the beginnings of a full featured open-source continuous scroll thumbnail component for Flex. It is rough right now, but I plan to polish it and make it something useful. This format is really appealing, as it gives the user a seamless view of a gallery, without any jumps or aggravating scroll bars. Up until now I have been using H and V Lists in flex for my thumbnailing, but they are ugly and don’t provide as rich of an experience.
The Scroll Panel from AFComponents was my first choice. It is a very nice component, well priced, and would be just what I need, if not for the fact that my project is open-source and using a commercial component sorta kills the whole thing. After scouring the internet I finally stumbled upon the work Peter Wright has put in on a perpetual scrolling list.
I’ve modified it to accept an XML list of image objects, as well as perform horizontally. It is also functioning as a slideshow, and I want to allow it to go either H or V depending on the need. It should shape up to be a nice reusable component. Much thanks to Peter for supplying the code to get me started.
