Customer has a regression (from P02 where this worked). The backing bean is ViewScoped and the @WindowsDisposed annotation is used. They have a NavigationHandler as well as a list of Messages in the view that is controlled by this backing bean. (bean is attached to the support case). Once the navigation is handled, the List of messages is no longer found (PropertyNotFoundException). Changing the backing bean to WindowsScoped works in this case. In P01 and P02 this worked with no changes to the backing bean and leaving it in @ViewScoped with the @WindowsDisposed annotation.

000 3 00 0000 2015-06-11 11:32:40.529 (JSFExceptionHandler:78) Error code: e3406fd1; Exception: javax.el.PropertyNotFoundException: /xhtml/messageTable.xhtml @15,69 value="#{messageQueuesBean.messageList}": The class 'org.icefaces.impl.application.WindowScopeManager$NOOPBean' does not have the property 'messageList'.

....
same application code was in the Fedex patch for P02, but just changing jars to P03 and this exception is thrown. It appears to only be a problem with ViewScoped beans using @WindowsDisposed. If the customer changes the bean to WindowScoped, then it works fine (survives the redirect).
