View source is enabled in the following example.

It seems that the dataChangeEffect effect was renamed to itemsChangeEffect in Flex 3 SDK build #184751 (Sat Oct 13 2007 — go to Adobe Labs: Flex 3 Software Development Kit (SDK) to download the latest nightly builds of the Flex 3 SDK). The previous example should still work as typed, although you’ll need to change the dataChangeEffect to itemsChangeEffect if you’re using a Flex 3 SDK build newer than October 13, 2007. For more information, see “dataChangeEffect is declared as a Style, not an Effect, and is not triggered by the dataChange event” in the public Flex bug base.
