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

[Dirk Eismann]

FYI: if an ArrayCollection is managed by a DataService, then the list property of the ArrayCollection is of type mx.data.DataList. This DataList holds a localItems Array which seems to track the references to the items available in this list. As the items are [Managed] (implement mx.data.DataService) they all have an uid property which is a String representation of the ID I need.   So it really seems as if it's enough to drill down to the localItems Array and look for the UID in question.   Dirk.

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. __._,_.___ -- Flexcoders Mailing List FAQ: http://groups.yahoo.com/group/flexcoders/files/flexcodersFAQ.txt Search Archives: http://www.mail-archive.com/flexcoders%40yahoogroups.com SPONSORED LINKS Software development tool Software development Software development services Home design software Software development company YAHOO!
