Overview of this book

PrimeFaces is the de facto standard in the Java web development. PrimeFaces is a lightweight library with one jar, zero-configuration, and no required dependencies. You just need to download PrimeFaces, add the primefaces-{version}.jar to your classpath and import the namespace to get started. This cookbook provides a head start by covering all the knowledge needed for working with PrimeFaces components in the real world. "PrimeFaces Cookbook" covers over 100 effective recipes for PrimeFaces 3.x which is a leading component suite to boost JSF applications. The book's range is wide‚Äí from AJAX basics, theming, and input components to advanced usage of datatable, menus, drag & drop, and charts. It also includes creating custom components and PrimeFaces Extensions.You will start with the basic concepts such as installing PrimeFaces, configuring it, and writing a first simple page. You will learn PrimeFaces' theming concept and common inputs and selects components. After that more advanced components and use cases will be discussed. The topics covered are grouping content with panels, data iteration components, endless menu variations, working with files and images, using drag & drop, creating charts, and maps. The last chapters describe solutions for frequent, advanced scenarios and give answers on how to write custom components based on PrimeFaces and also show the community-driven open source project PrimeFaces Extension in action.

Selecting rows in dataTable


There are several ways to select a row or multiple rows, such as line selection or selection with radio buttons or checkboxes, from the dataTable component. We will cover all the possibilities in this recipe.

How to do it...

To make a single selection possible with a command component, such as commandLink or commandButton, f:setPropertyActionListener can be used to set the selected row as a parameter to the server side.

<p:dataTable id="withCommand" var="car" value="#{dataTableController.cars}" rowKey="#{car.name}"selection="#{dataTableController.selectedCar}">
<p:column>
<p:commandButton value="Select" update=":mainForm:display" oncomplete="carDialog.show()">
<f:setPropertyActionListener value="#{car}"target="#{dataTableController.selectedCar}" />
</p:commandButton>
</p:column>
...
</p:dataTable>

The selection attribute needs to be bound to a Car reference in order to get the selected data.
