JSF PhaseListener called not at all or twice

Question

I have a PhaseListener, which seems to work correctly mostly => called mostly when expected and does what expected, but it is not called at all when the application is entered for the first time and in turn called twice on every call when once in the application (e.g. refresh).

The phaseId is: PhaseId.RENDER_RESPONSE;

MyListener has:

@Override
public void beforePhase(PhaseEvent event) { /* stuff */ }

@Override
public void afterPhase(PhaseEvent arg0) { /* Nothing done here */ }

I can see with debug-breakpoint that the 'beforePhase' is called twice when the page is refreshed (or page switched), but it's not called at all when the user is directed to this application from a link for example.

In faces-config.xml I have:

<lifecycle>
    <phase-listener>com.package.project.MyListener</phase-listener>
</lifecycle>

I am using GlassFish 3.1.2.2 and JSF 2.0 with PrimeFaces 3.5.
