5. Using the Outline view, locate the TileList component

in the FlickrRIA.mxml template.

6. Delete the code for the itemRenderer, Component, and

VBox components.

code is shown in Example 3-20.

Example 3-20. Referencing the itemRenderer

<mx:TileList width="100%" height="100%"

dataProvider="{photoFeed}"

itemRenderer="FlickrThumbnail">

The final code for FlickrRIA.mxml is shown in Example 3-21.
