Notes

Put some print statemants into your code and LifeCycleListener displays on the console in which phases of the LifeCycle of an XPage your code is executed.
We used this to identify if / when code is executed multiple times during a partial refresh that was triggered on datasources outside the refreshId

package your.pkg.name;

import javax.faces.event.PhaseEvent;
import javax.faces.event.PhaseId;
import javax.faces.event.PhaseListener;

public class LifeCycleListener implements PhaseListener {

      private static final long serialVersionUID = 1L;

      public PhaseId getPhaseId() {
        return PhaseId.ANY_PHASE;
    }

    public void beforePhase(PhaseEvent event) {
        System.out.println("START PHASE " + event.getPhaseId());
    }

    public void afterPhase(PhaseEvent event) {
        System.out.println("END PHASE " + event.getPhaseId());
    }

}

Add the following lines to your faces-config

  <lifecycle>
    <phase-listener>your.pkg.name.LifeCycleListener</phase-listener>
</lifecycle>
