First of all, I’d like to say that Spring Actionscript is an amazing framework, it works very well and I have being using it for some months with success.

I’ve seen this post some months ago and I’m developing an application using the suggested approach. But I have some problems with it and I’d like to hear your opinion about them.

The first one is the way you deal with the models. In your sample, EmployeeListPresentationModel is injected by the container and this object is responsible for instantiating the EmployeeDetailPresentationModel (which is not injected). The problem for me is that I usually need to access services and beans managed by the container in my Detail classes (like EmployeeDetailPresentationModel). For example, in my app I need to create a Travel and this Travel has an Itinerary. In order to create this Itinerary (or find an existent one) I need to use another service. To solve this, when I’m instantiating my Detail class I usually ask the container for an instance of the Detail class (I created a factory that has an applicationContext). But maybe there is a better solution. How do you handle this?

Another question is, why don’t you save the employee in the EmployeeDetailPresentationModel class? The way you have done works very well in your example. But if I needed to show the window to save employees in a different place? I would have to create listeners for the Detail class again? Wouldn’t it be better if the Detail class were able to save the employee?

And the last question is… you said that in big applications it might be necessary to disable autowiring. My question is… if I’m using too much this resource, my application will be slow just in the beggining? Or every time I need to inject an autowired class it will be more slow?

Thanks in advance, I really appreciate your work.

Awesome post. Is it OK to add style names to presentation model classes?

For example,

public var price:Number;
public var priceStyleName:String;
public var priceOverStyleName:String;
public var titleStyleName:String;

Can any one give me the link to donwload the source code of cairngorm — Cafe Townsend application.

since we can’t read the private variables of an object via reflection, we need to annotate a public variable which can then be autowired. It does not really matter if you annotate the getter or the setter, since these are treated as 1 accessor with read/write properties.

//[Autowired] <-why not work?
private var _presentationModel:EmployeeListPresentationModel;

[Autowired] //why it work? wot's the meaning of "autowired a (getter)funtion"?
[Bindable(event="presentationModelChange")]
public function get presentationModel():EmployeeListPresentationModel {
return _presentationModel;
}
…
//presentationModel using here

Hoping ur reply
