The framework still needs a lot of improvement. I used the import "as" functionality as we discussed in the previous post... it is slightly better but still not perfect.

I had lots of other issues and things to mention but i have completely forgotten them... probably because i have been typing unit tests for the past 5 hours!!

When they come back to be i will discuss them.

I would also like to take over as project lead, if that is ok with everyone?

4  Announcements and General Discussion / Architecture / stage logic in a proxy on: March 07, 2008, 06:06:01
Hi Cliff,

David Knape did a presentation on PureMVC using a Gallery application he had built.

In this application he uses a Proxy to store Stage logic such as the Stage "resize" event along with the scale and align properties etc. I would have considered a StageMediator to be the correct place for this logic.

He also retrieves the Stage object from the Proxy and calls its update() method, I can't help but feel that he should have dispatched a STAGE_UPDATE notification instead of gaining reference to the Stage object?

What are your thoughts to his approach? Does the Stage need a Proxy?

5  Announcements and General Discussion / Architecture / Proxy registration / Stage child management on: March 04, 2008, 02:59:39
Hello I have a couple of questions...

1) Should all proxies be instantiated and registered together when the application starts? Or can this be done as and when they are needed?

2) I work in a pure AS method, i do not use flex and i am trying to decide the best way to handle the creation and addition of new children to the stage etc...

if my AssetProxy executes:
facade.registerMediator(new ProgressBarMediator(new MovieClip()));

How should i handle the addition to the stage? Is it a bad idea for the Mediator to gain a reference to the stage? Should i send the child as the body of a notification? Should i create the movieclip and attach it to the stage from the command and THEN create the mediator with a reference to the new child?

I cannot seem to find an elegant solution to the management of children.

Many thanks in advance.

6  Announcements and General Discussion / Architecture / Preloader logic placement on: March 03, 2008, 08:55:37
I have a separate swf that contains all graphic assets for my app.

I cannot decide where the logic for preloading should go...

Somewhere it has to interact with a view to display the load progress.

Should the loading logic be placed into a proxy and dispatch a progress notification  ????

If so how would you use the "data" property of the proxy? to hold the "LoaderContentInfo" of the loaded swf and then provide a getAsset() method?

any thoughts?

7  Announcements and General Discussion / Architecture / Load View & Mediator based on Remote Proxy result on: January 23, 2008, 06:57:25

I am having trouble making a design decision...

When a user clicks on a category from the menu the following needs to occur:

1) The MenuMediator sends a notification which is bound to a LoadCategoryCommand

2) The LoadCategoryCommand needs to check which view and mediator to load

2 a) LoadCategoryCommand asks the CategoryProxy if the selected category owns any child categories. If so load the category view. If not -> 2b
2 b) LoadCategoryCommand asks the ProductsProxy if the selected category
owns any products. If so load the product view. if not -> 2c
2 c) LoadCategoryCommand asks the PageProxy is the selected category owns a page. If so load the page view. If not redirect the user / display error.

My problem is that the LoadCategoryCommand cannot listen for updates from the proxies, and the proxies must dispatch an event because they are loading XML from a remote URL...

Where should I handle the updates from the Proxies, and then decide which view to load.

8  Announcements and General Discussion / Architecture / sendNotification EventListener Bug on: January 21, 2008, 05:26:38

When using the following syntax there appears to be a problem.

var notification:String = "notificationString"
var data:Object = {'myVar':10}

When this notification is caught i add a child to the display list. The actionscript inside that child is ignored.

If i simply send the notification outside of the addEventListener everything works as expected.

There appears to be a bug in adding children to the display list from the onNotification method when the notification was dispatched from a native flash event.

I have also tried to define the function instead of typing it inline and the problem still occurs.
