public class GroovyPageView
extends org.codehaus.groovy.grails.web.servlet.view.AbstractGrailsView

A Spring View that renders Groovy Server Pages to the response. It requires an instance of GroovyPagesTemplateEngine to be set and will render to view returned by the getUrl() method of AbstractUrlBasedView This view also requires an instance of GrailsWebRequest to be bound to the currently executing Thread using Spring's RequestContextHolder. This can be done with by adding the GrailsWebRequestFilter.

Since:

0.4
