Thanks, yes I’ll be posting more in the future. In the mean-time, there’s a lot of great information on the asfusion site.

There is going to be some duplication in a manager and a presentation model; specifically the properties that you want to inject. In order to keep the managers and presentation models self-contained and re-usable, it makes sense to have corresponding properties in both places; that are injected. However, as long as the injected properties are the same type (ArrayCollection, Boolean, etc…), they don’t have to be identical; the targetKey and sourceKey of a PropertyInjector can be different. I chose to make them identical for this sample, so that it would be easy to follow the injection. If you wanted to use [Bindable] public var, instead of getter/setter, that would reduce the amount of byte-code. I choose getter/setter though, for performance and unit testing benefits.

Another thing to point out is that injection is one-way; not a reference. I think of it as the presentation model having an instance of the model object in the manager. If you change a model object in a presentation model, it does not automatically change the corresponding model object in the manager; that was injected. This comes in very handy when dealing with CRUD and multi-instance views.

Any other thoughts are more than welcome.

One question relating to the PM - I’ve used that in a Mate/Flex project which i’ve worked on and noticed a good deal of duplication of code. For instance, the following block of code is duplicated in your VideosManager and your VideosPresentationModel:

private var _searchResults:ArrayCollection = new ArrayCollection();

[Bindable( event="searchResultsChange" )]
public function get searchResults():ArrayCollection
{
return _searchResults;
}

public function set searchResults( value:ArrayCollection ):void
{
var oldValue:ArrayCollection = _searchResults;
if ( oldValue != value )
{
_searchResults = value;
dispatchEvent( new Event( “searchResultsChange” ) );
}
}

I’m not sure I see a good way to reduce duplication when you’re just basically injecting properties from the Manager to the PM, but was wondering if anyone else had any thoughts on the matter?
