ICEFaces request scope (and the consequences)

http://liferay-blogging.blogspot.com/2011/01/iceaces-request-scope-and-consequences.html

ICEFaces offers its own interpretation of the JSF request scope : the extended request scope.

This request scope lasts longer than the original request scope: It will continue to live when you are using partialSubmit controls and it will continue to live when you are using non-redirect navigation rules.

This means for example, that when you are navigating back and forth within two pages your beans won´t be recreated which then means that you can´t put code into the constructor of your beans because it will only be executed once.

But sometimes you have the need for backing beans to be recreated every time a page is requested. To avoid having to deal with JQuery you have two possibilities:

What to do when you have a simple ICEFaces application

If you have a simple ICEFaces application that is NOT running in a portlet environment, you can just add a redirect to your faces-config navigation rule:



This redirects to the specified pages, thus leaving the extended portlet request and therefore recreating your managed beans.
