RE: [flexcoders] Re: FDS - how do I manage a single item?

[Jeff Vroom]

There are a few examples in the flexcab sample (samples/dataservice/flexcab).  Here’s 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");                                             }));   Jeff   From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Dmitry Miller Sent: Tuesday, August 01, 2006 2:20 PM To: flexcoders@yahoogroups.com Subject: [flexcoders] Re: FDS - how do I manage a single item?   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?
