this is the code from MyFaces, and it shows that the phase listener
should only be added once:
// add phase listeners
for (Iterator iterator =
_dispenser.getLifecyclePhaseListeners(); iterator.hasNext();)
{
String listenerClassName = (String) iterator.next();
try
{
lifecycle.addPhaseListener((PhaseListener)
ClassUtils.newInstance(listenerClassName));
} catch (ClassCastException e)
{
log.error("Class " + listenerClassName + " does not
implement PhaseListener");
}
}
I shortly looked over the rest of the code, don't see any problems there...
Maybe you got two faces-config.xml files in different directories and
this is why they are called twice?
