Bugfix
If you look at a process object in a historical state where a person is an actor but no longer exists in current, a NullPointerException occurs:
java.lang.NullPointerException: Cannot invoke "com.top_logic.knowledge.wrap.person.Person.getRepresentativeGroup()" because "currentResultPerson" is null at
