INFO: AFTER UPDATE_MODEL_VALUES(4) 16/11/2005 00:45:12 com.traleva.erp.web.util.PhaseTracker afterPhase INFO: AFTER RENDER_RESPONSE(6) Hi,   I am having this very puzzling out of order execution. My setup is as following:   I have 4 filters, in this order – SecurityFilter, HibernateFilterLong, JSF-Spring filter, myfaces ExtensionFilter.   Now look at the following trace, my comments in brackets. Can somebody please explain?   Regards, Yee   -------------------------------------------------------------------------------------   16/11/2005 00:45:12 com.traleva.erp.web.util.PhaseTracker beforePhase INFO: BEFORE INVOKE_APPLICATION(5) 00:45:12,975 DEBUG FacesServlet:132 - service end   (myfaces ExtensionFilter is finishing in the middle of JSF life cycle!
