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.

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.
