Elephant ,
if you are considering each SWF as a module within itself perhaps the multicore version may help in this situation.The stage may be considered the main core and each "View SWF module" additional cores.

If you are new to pureMVC this may appear a little daunting and it may help reviewing other posts on "Modularity" If you do decide to investigate this further

Found this, not sure if this is related to your problem. but may help?

Thanks David, great job,
Thanks also for your reply to my post in regarding additional requests (reCap for thread)

"user defined strings that can be used in the templates."
"VO's could be generated from an SQL not just php"
"AS3 only generation not just FLEX"
"Output ready to run option"

As I use it more I have also found:
If AS3 output is generated a template for the mainframe.as code (or perhaps called Application.as)
Could the empty MainProxy (generated by default) be changed to ApplicationProxy ?
also can the template names that are referenced be changed by the user
this would help in multi template handling.
i.e. I'm using MultiCore templates as well as Standard pureMVC.

Thanks Again David
Nice Job :-)

I have ended up using MicroOLAP Database designer for getting proxy designs and VO's
then feeding PHP output into FCG (Flex Code Generator with some adjusted templates) to output pureMVC source, needs a little re-work for pureAS3, but saves quite a bit of time.

Hi Alex,
I feel this depends on the application, the Mediator(controller) has a crucial job of managing UI components, its dealings with the proxy are determined by its need for data storage and manipulation.This coupling can be tight or loose depending on the granularity you may require in your application.
I tend to bias slightly tighter connections due to my C++ optimization fetish's, but through my study off MVC patterns I realize the value of a looser coupling and try to design accordingly.

I find when starting my first design phase, granularity starts to become more apparent.

• Many UI components? (will it be modular and How should this breakdown?) (Commands? mediators?)
• large amount of data?  (startupManager?, How many proxies?)
• need for VO's? (whats getting passed around the application?)
• Login ? (yet another proxy? or VO [value object])
• Preloading?

etc.

Thanks cliff, onRegister sounds a better place.
I left the Post in, for others to see and start a useful dialogue, I have not seen any examples of using "OnRegister" in any standard vision examples as yet.

This point seems a little unclear in the docs, perhaps a good one for the design docs for multicore :-)

Thanks again

Trying to understand this error:

EDIT: FIXED

:

override public function initializeNotifier(key:String):void

A better Fix: (based on Cliff Comments)

:

{
// Retrieve reference to frequently consulted Proxies
stageProxy = facade.retrieveProxy( StageProxy.NAME ) as StageProxy;
}

Might need a bit more info on how you are setting up the proxy for the ProjectVO and when your initializing it.

could the STL (standard template Library) be used for this functionality ?
Or is that what you mean by generics?

T

Users should not look to the utility to provide graphic 'pre-loader' status type display.

why not?, seems most of the code is already in place to facilitate this, and would certainly add another dimension to an already nice utility.
This is also a very common problem that face pure AS3 coders.

On a side note:
if the startup manager is allowing reloading "using utility more than once from within an app"
perhaps appropriate notification would also be sent ".RELOADED", also tracking its reload of  n times. ?

T

Hi Steve,
app = ApplicationFacade.getInstance(Application.NAME)  or am i missing something?

Curtis [Trilec]

Hi Riafan,
It my understanding that components can exchange data with the mediator using events or custom typed Objects.
so using a VO should be fine and sounds like better for your requirements (which is what its all about :-) )

Curtis [Trilec]

Perhaps,
ProxyPreloadManager as opposed to  ViewStateManager (the next utility after this one :-) )

On a side note:
Do you think it will make much difference If I adjusted the startupmanager to use multicore so im not loading a single and multi versions into the app or
should startupmanager detect what you use and use that or
two versions with import adjusted or
your crazy Curt, just load the two and sit back down.

for reference:

:

package org.puremvc.as3.utilities.startupmanager.controller {
//import org.puremvc.as3.interfaces.ICommand;  //replace
import org.puremvc.as3.multicore.interfaces.ICommand; //exampe
etc ...

public class StartupResourceLoadedCommand extends SimpleCommand implements ICommand {T

Hi, Steve/Cliff
So True, still trying to grasp pattern concepts, have only just managed to complete a multicore prototype after spending three weeks just reading forums and source code... lol
I still find it a little ambiguous as to where one would use the startup manager (I was looking for it to fulfill the role of asset pre-loader)
and may be overkill for some development, but at which point?, and as I've posted before, means a proxy would contain GUI style elements or animation which views may need to build other GUI elements (styles manager proxy loading assets)? 
(hoping with a little more research/testing I will find where it fits my needs if any)

On a side note I feel the same for needing state machine utilities and implementation guidelines, there was some good discussion about this in previous state machines posts but seems to have become quiet.

Curtis [Trilec]

Hi Cliff,Steve
Did you look into the HMVC pattern (layered pattern for developing strong client tiers) (close to PAC Pattern)

http://www.javaworld.com/javaworld/jw-07-2000/jw-0721-hmvc.html?page=3

Interesting approch for a structured client-tier architecture and handling the universal question off where do I put Menu, Status, Nav, and Content class assignments within a MVC pattern.
But as I see it, Multicore can handle this situation as long as the definition of the "touch points" is well-defined and perhaps helper functions added to address this communication in a predefined manner.?

We definitely need a few more multicore examples, I feel this is a real hidden strength of pureMVC and also seems similar to HMVC approch :-)
