I am aware that two arraycollections pointing to the same source contain references to the same set of objects. Let me clarify that I am speaking of an arraycollection that is managed by a custom assembler in LCDS 2.51. New items are being added to this arraycollection by a server-side process. The users want only to see the most recent 200 records.
Now the source property of a managed arraycollection is null. The arraycollection.list.localItems property might possibly be used as you suggest, but I think any slice of this array would be static. As new items are added to the managed arraycollection, I would have to manually copy them to the collection actually bound to the grid and then manually remove the oldest items. --- In [email protected], "Tracy Spratt" <[EMAIL PROTECTED]> wrote: > > Two ArrayCollections pointing at the same source should be working with > references to the items, so you shouldn't need to "transfer data".
