Jeff, hi
I am trying to retrieve item by its id. And I tried your suggestion
yesterday.
var ir:ItemReference = ds.getItem({id:userId});
Now, given the item reference (ir) how do I connect ir to the actual
variable (me)? When I tried me = User(ir.result); Flex started
compaining.
Could you, please, give a code snippet?
Thanks a lot

Either with dataService.getItem, if the item exists and you have its
id or dataService.createItem if the item does not exist and you want
to create a new one.
If you need to actually execute a query to retrieve the item (e.g.
you are trying to retrieve a User by the lastName), you have to use
the fill method to pass in the parameters and just have that fill
method return a Collection with just one item. In this case, the
fill method returns an AsyncToken whose responder will be called when
the fill results are returned to the client. At that point, you
could look at the filled array collection and call getItemAt(0) to
get the first item in the list.

There are a few examples in the flexcab
sample (samples/dataservice/flexcab). Heres a snippet from one of
these:
var
itemRef:ItemReference =
ServiceLocator.getInstance().cabService.getItem({name:
newCab.name}, newCab);
itemRef.addResponder(new ItemResponder(
function (resultEvent:ResultEvent, token:Object=null):void
{
cab = itemRef.result as Cab;
// . Second rpc call snipped from here
},
function (faultEvent:FaultEvent, token:Object=null):void
{
Alert.show(faultEvent.fault.faultString, Error Logging In);
}));
