Is it possible to load dynamically a Phase Listener with JSF 1.2?

Question
I have been using a Phase Listener to debug my JSF application.
Now I'm wondering if it's possible to load it dynamically depending on, for example, a system property is set or not (so I can commit the thing, and not worry about having to remove it before deploy in production).
Does anyone know if there is a way to do that in faces-config.xml
?
Thanks in advance!
Solution
You can add phaselisteners dynamically by UIViewRoot#addPhaseListener()
.
PhaseListener phaseListener = new YourPhaseListener();
FacesContext.getCurrentInstance().getViewRoot().addPhaseListener(phaseListener);
You've only to do it on a per-view basis. It's perhaps better to keep the phase listener registered and let it take actions only when the desired system property is set or not.
