Hi Bart, Thanks for sending those logs. I believe this is a bug fixed in LC DS 2.6 which is now available on the adobe site. We also have a hotfix for it on 2.5.1 - contact me off list if you need a copy of that.

Kind Regards Bart Ronsyn This error can occur when you access an unpaged item when paging is enabled of course, but given that you are running that code in the result handler it seems like this is not the problem (unless the result event is being delivered for another call on that data service). It might also happen if the identities are not getting defined properly in ActionScript. If you add <mx:TraceTarget/> and send along the resulting flashlog.txt, we can see what is happening from that. Jeff From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of Bart Ronsyn Sent: Friday, July 25, 2008 8:12 AM To: [email protected] Cc: Bart Ronsyn Subject: [flexcoders] LCDS - Data Management Service Problem Hello, I have a Data Management Service that uses a managed ArrayCollection of users. When a user is added by one client, the other clients are notified by the Data Management Service, and I want to loop through the ArrayCollection, using the code below, but I always get the following error : Error: Item requested is not available. A request for the item is now pending. at mx.data::DataList/http://www.adobe.com/2006/flex/mx/internal::requestItemAt()<http://www.adobe.com/2006/flex/mx/internal::requestItemAt%28%29>[C:\depot\flex\branches\enterprise_bridgeman\frameworks\mx\data\DataList.as:949] at mx.data::DataList/getItemAt()[C:\depot\flex\branches\enterprise_bridgeman\frameworks\mx\data\DataList.as:261] at mx.collections::ListCollectionView/getItemAt()[E:\dev\3.0.x\frameworks\projects\framework\src\mx\collections\ListCollectionView.as:431] ... This error occurs when the line "users.getItemAt(j) as User" is executed. It seems that although the length of the ArrayCollection users equals 1, I can not get the Item at position 0. Maybe the update of the ArrayCollection is not yet finished ? How can I loop through the ArrayCollection upon changes ? ... [Bindable] private var users:ArrayCollection; private var ds:DataService; private function init() { users = new ArrayCollection(); //users.addEventListener(CollectionEvent.COLLECTION_CHANGE, refreshUsers); ds = new DataService("user"); ... ds.autoSyncEnabled = true; ds.fill(users); ds.addEventListener(ResultEvent.RESULT, refreshUsers); } private function refreshUsers(evt:ResultEvent):void { trace ("refreshUsers" + users.length); for(var j:uint=0; j < users.length; j++) { var user:User = users.getItemAt(j) as User; showUserProfile(user); } } ...
