> Key: MYFACES-3179
> URL: https://issues.apache.org/jira/browse/MYFACES-3179
> Project: MyFaces Core
> Issue Type: Bug
> Components: JSR-314
> Affects Versions: 2.0.7, 2.1.0, 2.1.1
> Environment: Tested on Tomcat 7
> Reporter: Deryk Sinotte
> Assignee: Leonardo Uribe
> Fix For: 2.0.8, 2.1.2

> Attachments: listeners.zip

>
> I've developed a test case (which will be attached) which is a simple JSF app
> that has 3 different methods of registering SystemEventListeners for
> PostAddToViewEvents:
> 1) via @ListenFor annotations
> 2) via definition in faces-config.xml
> 3) via programmatically adding the listener through an eagerly created
> application scoped bean
> Then I ran this tst case with the following JSF implemenations:
> * Mojarra 2.1
> * MyFaces 2.0.7
> * MyFaces 2.1.0
> * MyFaces 2.1.1
> The behaviour can be summarized as follows:
> Method 1 - Annotations
> All implementations: The listener instance is never constructed or used.
> (Perhaps it's a limitation of the annotation processing in Tomcat?)
> Method 2 - Defining in faces-config.xml
> Mojarra 2.1: An instance of the listener is created and used appropriately.
> MyFaces 2.*: An instance of the listener is created but the isListenerFor()
> and processEvent() methods are never called.
> Method 3 - Programmatic registration
> All implementations: An instance of the listener is created and used
> appropriately.
> So the question is why, when the listeners are defined in the faces-config
> file, are the listeners created but never called. Other MyFaces JIRAs that
> might have some relevance:
> https://issues.apache.org/jira/browse/MYFACES-2509
> https://issues.apache.org/jira/browse/MYFACES-2638
> Bottom line is that only the programmatic approach appears to be reliable
> across the 2 implementations.
