RE: [flexcoders] FDMS: check, if an item exists on the client?

[Dirk Eismann]

Hi Jimmy,   I don't think there's a getItem() method on ArrayCollection. There's only getItemAt() but that's useless as I don't have the index of the item.   Actually, all I know about the item is the unique ID (i.e. the PK from the DB table) so what I need is something like     myArrayCollection.getItemByUID(uid);   where uid is an Object containing the unique ID, e.g.     var uid:Object = {organization_id: 123};   Makes sense?   So far I have found no way to query a DataStore/Arraycollection/DataList/whatever for an item by passing in the unique ID withouth going to FDMS if the item is already living on the client.   Dirk.

I think what you are looking for is:   myArrayCollection.getItem( x );   Assuming myArrayCollection was populated by the fill() method of a DataService.   Dimitrios Gianninas RIA Developer Optimal Payments Inc.   From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Dirk Eismann Sent: Friday, August 25, 2006 10:43 AM To: flexcoders@yahoogroups.com Subject: [flexcoders] FDMS: check, if an item exists on the client? Is there any way in FDMS to get an item without really going to the server if it's on the client already? I found that calling dataService.getItem(uid) always goes to the server, even if the item in question is available on the client. This is unnecessary overhead IMHO if the item is available in the DataStore/Collection. Do I have to implement my own lookup strategy here??? Thanks, Dirk.
