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.
I call ArrayCollection.addItem() to add either ParentObj or ChildObj
to the tree, and both are called after the filter is defined. In
fact, I call the ChildObj insert right after the ParentObj insert.
Basically, I want to hide all top-level nodes in the tree, but the
filter function isn't even called for those nodes.
