Heya,
I was looking for one too and there doesn't seem to be one. I'm able to
currently encapsulate Create/Read/Delete actions in commands, but I
haven't yet found a reliable way to encapsulate Updates in a command.
Everything else works very nicely.
Example of fill:
var ev:ProductEvent = new ProductEvent(ProductEvent.FIND_ALL);
ev.collection = model.products;
CairngormEventDispatcher.getInstance().dispatchEvent(ev);
Execute:
public function execute(event:CairngormEvent):void {
var ds:DataSource = new DataSource("productHome");
var ev:ProductEvent = event as ProductEvent;
ds.fill(ev.collection); // event is carrying a reference to an
arbitrary collection contained in your model
}
Example of createItem:
var ev:ProductEvent = new ProductEvent(ProductEvent.INSERT);
ev.product = someProduct;
CairngormEventDispatcher.getInstance().dispatchEvent(ev);
Execute:
public function execute(event:CairngormEvent):void {
var ds:DataSource = new DataSource("productHome");
var ev:ProductEvent = event as ProductEvent;
ds.createItem(ev.product); // event is carrying a reference to a
product bean
}
Example of deleteItem:
var ev:ProductEvent = new ProductEvent(ProductEvent.DELETE);
ev.product = someProduct;
CairngormEventDispatcher.getInstance().dispatchEvent(ev);
Execute:
public function execute(event:CairngormEvent):void {
var ds:DataSource = new DataSource("productHome");
var ev:ProductEvent = event as ProductEvent;
ds.deleteItem(ev.product); // event is carrying a reference to a
product bean
}
When you find a good way to handle updates, you let me know ;)
Currently there is no fine-grained approach to updating only one
specific record manually, which kinda sucks.

Subject: [flexcoders] Cairngorm FDS Sample
Hi,
We are planning to use Cairngorm in our flex project which uses FDS. I
tried looking around for samples that use FDS(not remoting) but no
luck. From www.cairngormdocs.org I am able to find number of sample
that use webservices, remoting etc..
Can anyone suggest a sample Cairngorm app that uses FDS(Data
services). I am trying to see how FDS methods like fill etc. fit into
cairngorm model
Thanks,
ANAND.
