Apache MyFaces 1.2 Web Application Development

Overview of this book

Hypes and trends (such as Web 2.0) cause a change in the requirements for user interfaces every now and then. While a lot of frameworks are capable of meeting those changing requirements, it often means you as a developer need in-depth knowledge of web standards, such as XHTML and JavaScript. A framework like Apache MyFaces that hides all details of how the page is rendered at the client and at the same time offers a rich set of tools and building blocks could save you a lot of time, not only when you're building a brand new application but also when you're adapting an existing application to meet new user interface requirements.This book will teach you everything you need to know to build appealing web interfaces with Apache MyFaces and maintain your code in a pragmatic way. It describes all the steps that are involved in building a user interface with Apache MyFaces. This includes building templates and composition components with Facelets, using all sorts of specialized components from the Tomahawk, Trinidad, and Tobago component sets and adding validation with MyFaces Extensions Validator.The book uses a step-by-step approach and contains a lot of tips based on experience of the MyFaces libraries in real-world projects. Throughout the book an example scenario is used to work towards a fully functional application when the book is finished.This step-by-step guide will help you to build a fully functional and powerful application.

Using extended versions of standard components


As mentioned in the introduction, Tomahawk offers an extended version of every component that is in the standard JSF component set. The following table lists the extra attributes that can be used on all Tomahawk components:

Attribute

Type

Description

disabledOnClientSide

boolean

If the standard disabled attribute is set to true, the component will be disabled and the value of the component will not be submitted on a postback of the containing form. This disabledOnClientSide attribute will not only render a disabled component, but will also render a hidden input field, causing the value of the component to be submitted with the containing form.

displayValueOnly

boolean

If set to true, only the value of the component is rendered, without an input widget. Of course,<h:outputText> tag could be used instead, but by using this attribute, this behavior can be activated through Expression Language.

displayValueOnlyStyle
