> Following scenario, two pages with implicit navigation. A prerender view system event handler set over
> <h:head>
> <title>Facelet Title</title>
> <f:metadata>
> <f:event listener="#{pageHandler.prerender}" type="preRenderView" />
> </f:metadata>
> </h:head>
> Now the prerender event is called:
> a) if I go via http get into the page
> b) If I execute actions which stay on the page
> The event handler however is not called
> if I navigate into the page via an implicit (maybe also explicit) navigation case.
> A quick test revealed that the event handler is called in three cases in mojarra and I assume our behavior is faulty
> and the behavior from mojarra is the one compliant to the spec.
> I am setting the priority to major because the prerenderview event is very important in certain app classes which use callbacks to this event
> to deal with auto display mechanisms and with data loading in certain app states.
> Here is the complete example:
> page1:
> <?xml version='1.0' encoding='UTF-8' ?>
> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
> <html xmlns="http://www.w3.org/1999/xhtml"
> xmlns:h="http://java.sun.com/jsf/html"
> xmlns:f="http://java.sun.com/jsf/core">
> <h:head>
> <title>Facelet Title</title>
> <f:metadata>
> <f:event listener="#{pageHandler.prerender}" type="preRenderView" />
> </f:metadata>
> </h:head>
> <h:body>
> <h:form>
> Hello from Facelets
> <h:commandLink action="page2" value="page2"/>
> </h:form>
> </h:body>
> </html>
> page2:
> <?xml version='1.0' encoding='UTF-8' ?>
> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
> <html xmlns="http://www.w3.org/1999/xhtml"
> xmlns:h="http://java.sun.com/jsf/html">
> <h:head>
> <title>Facelet Title</title>
> </h:head>
> <h:body>
> <h:form>
> Hello from Facelets
> <h:commandLink action="page1" value="go to page 1" />
> </h:form>
> </h:body>
> </html>
> and the corresponding bean:
> @ManagedBean
> @RequestScoped
> public class PageHandler {
> public void prerender() {
> System.out.println("Prerender View");
> }
> }
