Last paragraph

It wasn't apparent to me that the following paragraph First, cut the entire <mx:Script/> tag from the ContactManager application and all the ActionScript code within it. Then paste this into the ContactViewer component, right after the opening <mx:Panel/> tag. indicated that I should also move all the Validators and Formating code in the ContactManager and add it to the ContactViewer. The ending sentence eludes to this though: Because this code is all for validation and data massaging, it makes sense to have it encapsulated within this component and not in the main application. This appears to be where the user should do this step since it's not outlined anywhere else.

Since you don't introduce Objects and Classes until page 54, I think your sudden use of the word "class" on page 52 in the "Methods" section, with neither an explanation nor a forward-looking "see" reference, is confusing for someone with "no experience with...programming in general" (part of your target audience, according to "Who This Book Is For", p. xiv).

2nd paragraph

"One method you've already learned about is addEventListener()" is confusing. We haven't discussed Event Listeners yet. According to the index we won't get there until page 60.
