Hi Allen,

I agree that it is not a perfect solution right now since you need to update 2 places. If only we would have some class loading mechanism in the flash player, that would solve a lot of our problems. Externalizing the controller does have the advantage that you can remap the events/commands without recompiling your app. I haven’t had a use-case myself where I needed that, but I’m sure it could come in handy one day

I really like your blog btw! Keep up the good work!

regards,
Christophe

Hello Christophe,

I like what you are doing with Prana it seems like it can help quite a bit.

This approach does remove some boilerplate code, but it still leaves two places that we need to add new commands- the reference listing and an external XML file. I don’t know which one I would rather have: less boilerplate code, or less places to update.

Best,
al

Hi Paul,

every object that you want to instantiate dynamically needs a class that is compiled into the swf file. To do this, you need to force compilation of that class by either making a reference to it or by adding it to the compiler settings.

Hi,
I read some articles about the reflection in AS3. It is said (and I’ve tried) that when using getDefinitionByName to generate an object(as is used in Utils.forName in Prana), only internal AS classes will succeed. while using custom class as the parameter for the method:getDefinitionByName, error will occur, unless users have declared one object of this custom class.(Please refer to http://weblogs.thekeunster.com/?p=10)

Can you please describe how you deal with this? Thanks

It’s really cool what you’ve done with implementing a IoC framework for ActionScript. Especially the Cairngorm framework is a dinosaur framework that really should be rewritten from the ground up with something like Prana powering it. The amounts of pointless boiler-plate code you have to write with Cairngorm is just ridiculous…

Hi,

this was mentioned in the post. You actually don’t need to make new instances of the classes that you want to include. Just referencing them will force the compiler to add them to the swf.

private var _commands:Array = [GetProductsCommand, AddProductToShoppingCartCommand, DeleteProductFromShoppingCartCommand, FilterProductsCommand, SortProductsCommand, ValidateOrderCommand, ValidateCreditCardCommand, CompletePurchaseCommand];

hello,i found some problem in your ioc patten.

that as3 compiler mxmlc will not compile your class include to swfï¼Œ if it havnt been new in your projectã€‚

so,it’s i found problem. or, we can use mxmlc -include [class],but it’s so bother.

i’m sorry for my poor english.
