Hello Danny,
I'm not 100% sure, but as far as I understood ActionListeners and
managed-beans are not the same this, so the aren't created by the same
Factory.
Therefor it would logical to have different instances of the class.
I didn't try it with ActionListeners yet, but I did ran into the same
sort of problems with ServletFilter, which are being instanciated by the
servlet-container and not 'properly' retrieved from an IoC-container
causing the dependancy injection to not be executed. Since the lifecycle
of an ActionListeren doesn't have any init-method or something alike I
suggest you do the following:
1) Add a boolean isInitialized = false;
2) In the implementation of processAction(javax.faces.event.ActionEvent
event) method check if object isInitialized. If not run a custom
initListener-method()
3) Write the custom initListener, which retrieves the dependancues from
the IoC-container you are using. For Spring this would be something
like:
private void initListener() {
ServletContext servletContext = (ServletContext)
FacesContext.getCurrentInstance().getExternalContext()
BeanFactory beanFactory =
WebApplicationContextUtils.getWebApplicationContext( servletContext );
myService = (ServiceInterface) beanFactory.getBean( "serviceId" );
}
I hope this helps get you your ActionListener working.
With kind regards,
Marco

Hi,
I want to use my ActionListener as a Managed-Bean because I need to
inject a service to the listener.
In the invoke-application-phase the injected service is null, why?
So I added a breakpoint to the setter of the property. And so the setter
will be invoked, but the JavaObject-ID isn't the same as in Phase 5!
Does the managed-bean factory create a proxy for the managed-beans or
listener-classes?
Where is the break in my mind?
Thanks
kind regards
DaWorm
