Wicket Plugin

Wicket Plugin

If you want to use the Wicket framework as an alternative view rendering technology on top of GORM then this plug-in is for you

Supports wicket version 1.4.9

Plugin is up-to-date for Grails 1.3 using Groovy 1.7

Anonymous inner classes support was added in Groovy 1.7 making it possible to use pure Wicket syntax without any workarounds.

Features

The plug-in provides the following features:

  1. Hot reloading of the WicketApplication class
  2. Hot reloading of Wicket Pages and views
  3. Integration with GORM and the underlying Spring container

Installing the Plug-in

The plug-in is available from the Grails central repository and can be installed with: 

grails install-plugin wicket
The installation process will create a class called WicketApplication at the location grails-app/conf/WicketApplication.groovy

Pages and Views

The plug-in provides a new directory under grails-app/pages where you should create your Wicket page classes which should end in the convention "Page" if you want hot reloading to happen. For example: 

import org.apache.wicket.markup.html.WebPage
import org.apache.wicket.markup.html.basic.Label
import org.apache.wicket.PageParameters
public class HelloPage extends WebPage
{
    public HelloPage(final PageParameters parameters) {
        add(new Label("message", "If you see this message wicket is properly configured and running!"));
    }
}
Now define the view in grails-app/views: 
<html>
<body>
    <span wicket:id="message">Message goes here</span>
</body>
</html>

Running the Application

Start-up your app with grails run-app then access http://localhost:8080/wicket-example/app
