Description

Steps to reproduce:

Create a tree object and supply it with an ArrayCollection dataprovider. Add a filter function to the dataprovider that filters out some elements from the list. Call the refresh() method on the dataprovider.

Here's a small application that shows the problem.

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="horizontal">
<mx:Script>
<![CDATA[
import mx.collections.ArrayCollection;

private function doIt() : void

{ _ac.filterFunction = filt; _ac.refresh(); }

private function filt( o : Object ) : Boolean

{ return ( o as String ).match( new RegExp( "o", "i" ) ) != null; }

[Bindable]
private var _ac : ArrayCollection = new ArrayCollection( [
"one", "two", "three", "four", "five" ] );
]]
>
</mx:Script>

<mx:Button label="do it" click="doIt()"/>
<mx:List width="100" height="200" dataProvider="{_ac}"/>
<mx:Tree width="100" height="200" dataProvider="{_ac}"/>
</mx:Application>

Actual Results:

Tree does not update.

Expected Results:

Tree should update by removing filtered out item.

Workaround (if any):

Reset the tree's dataprovider. E.g. tree.dataProvider = dp
