En af de væsentlige ting som foretages af BaseSiteComponent klassen er at fange
den SiteComponentException, som kastes under initialize fasen, og generere en label
med fejlbeskeden, samt en knap som administratoren kan benytte til at løse
problemerne. NewsArchiveComponent klassen behøver derfor kun at implementere
”forretningslogikken”, og nedarver præsentationskoden.
