Chapter 3 describes the various features of Tapestry like page templates and page
classes, expansions, components, and so on. It actually makes you comfortable
working with Tapestry, creating a bare-bones project, handling expansions and
components, navigating between pages, and creating and using Application State
Objects (ASOs).

Chapter 4 examines some of the components in Tapestry like TextField,
PasswordField, Label, PageLink, ActionLink, Loop, If, Output, RadioGroup and
Radio, Checkbox, Submit and Select. These are simple components which map
almost directly to HTML controls and elements. These are normally used on every
page of a Tapestry web application and help you in creating a functionally-rich
user interface.
Chapter 5 examines some of the more advanced components such as Grid,
BeanEditForm, DateField and FCKEditor. Using these, you can build some
functionally-rich user interfaces. You can easily implement repeating patterns like
tables and dates on a web page.
Chapter 6 covers that feature of Tapestry 5 which prevents a user to input erroneous
data on a web page. This feature, which is called user input validation, not only
identifies the erroneous field and marks it in some way, but may also explain why it
is erroneous.
