Thanks, Oleg, Jeff.
In reality the thing that comes back after querying my database is an
ArrayCollection of strongly typed objects (value objects?). These objects have
a linear (non-hierarchical) structure but I want to use one of the properties
(the "group" property) for the parent nodes in a Tree component.
Should I be looking at creating a custom data descriptor or a custom object
that implements the ICollectionView interface (does that mean create a custom
Tree component?).
I just want to make sure I'm doing the right thing, since either approach seems
to involve quite a bit of ActionScript.
Thanks again.

You can also create a custom data descriptor and set the dataDescriptor
property of the tree component. See http://livedocs. adobe.com/ flex/3/html/
