It turns out that filtering out the parent node hides all the
children too, so I guess this isn't what I want after all.

When I try this, the filter function isn't called for top-level
items. It's called for all child nodes in the dataProvider, but not
for the parent node. Any idea why this might be, or do you need a
code sample?

Interesting, I would think that the opposite would occur; if you're
using something like: return item.myfield==whatever;. Sure, post your
filterFunction; as well as a basic idea of the collection's structure.

My filter function is really simple. Something along these lines:
private function filterFunc(item:Object):Boolean

return item is ChildObj;

The dataProvider is an ArrayCollection containing ParentObjs.
ParentObj extends ArrayCollection, and contains ChildObjs.

Are you calling ArrayCollection.refresh() after you finish adding the
parent and children objects?

No, I never call refresh(). Here's the sequence:
1) Set the filter function.
2) Add a parent object [filter function is not called]
3) Add a child object [filter function IS called]
I've tried adding parents and children later on too, and the filter
function is still only called for children.
Anytime that you use a filterFunction or sort on an ArrayCollection,
it won't be executed until you use call the refresh method.
Basically you're saying, ok filter and sort my collection now. It
doesn't happen automatically. After #3, and anytime that items are

Note that if I choose to filter out all the child nodes, it works
perfectly. It's only the parent nodes I can't filter, because the
filter is never called for them.

Also, is the filterFunction on the correct ArrayCollection (the main one
and not the extended one)? The correct order would be:

ICollectionView or a filterFuncton can work for this; if you don't want
to mess with the underlying source.
